Blood and lymphoma cancers or hematologic malignancies include leukemia, lymphoma and myeloma. These cancers affect the lymph nodes, blood cells and organs of the immune system.
Cancer can develop within the brain or spinal cord or can travel to the brain or spinal cord from another part of the body.
Digestive or gastrointestinal cancers affect the digestive system and are among the most common forms of cancer.
Head and neck cancer affects the mouth, throat, sinuses, nasal cavity, larynx and salivary glands.
Skin cancer is a serious disease that can affect anyone. It is the most common form of cancer. If caught early, skin cancer can often be treated with success. But in some cases, it is life-threatening. To play it safe, start doing monthly skin checkups. If you see any changes in your skin, contact your doctor right away. Read on to learn more.
Basal cell cancer is the most common skin cancer. Lesions often appear on the face, ears, neck, trunk, or arms. Varying in color, these lesions may be waxy, pearly, scaly, or scarlike. Tiny blood vessels may be seen through the lesion’s surface. These lesions sometime bleed easily and might not heal well.
Melanoma is a more dangerous type of skin cancer because it is more likely to grow and spread than basal or squamous cell cancers.. A melanoma lesion’s borders are often poorly defined. It is often brown or black, but it may be mixed in color. The shape and size of melanoma lesions tend to differ from 1 side to the other.
Squamous cell cancer is also a common type of skin cancer. Lesions often form on the face (commonly on the lips), ears, neck, hands, or arms. The lesions are firm, red bumps or flat, scaly, crusty growths.
Bowen’s disease is an early stage of squamous cell cancer. The lesions are usually red, crusty, scaly growths with well-defined borders.
There are other types of skin cancer as well, including Merkel cell cancer and cutaneous (skin) lymphomas, but these cancers are rare.
Actinic keratosis is not skin cancer. It is a common, precancerous skin change that can turn into a squamous cell skin cancer if left untreated over a long period of time. Actinic keratosis lesions tend to appear on sun-exposed parts of the body. They can be reddish-brown or skin-colored. These lesions are most often raised, scaly, and rough, like sandpaper. In some cases, actinic keratosis lesions are painful. Getting early treatment for actinic keratoses almost always cures the lesions. Treatment includes freezing them with liquid nitrogen or applying a topical prescription medication. You may need a biopsy so your health care provider can find out whether it is advanced actinic keratosis or an early skin cancer.
Skin cancer is one of the most common types of cancer. Although this type of cancer can be treatable, the number of melanoma cases is on the rise in the United States
Usually caused by cancers that have spread throughout the body, bone and soft tissue cancers are complex and require expertise from many types of specialists available through our Complex Joints & Musculoskeletal Tumors
Having breast cancer means that some cells in your breast have changed and are growing out of control. Learning about the different types and stages of breast cancer can help you take an active role in your treatment.
Your entire body is made of living tissue. This tissue is made up of tiny cells. You can't see these cells with the naked eye. Normal cells reproduce (divide) in a controlled way. They grow when your body needs them, and die when your body does not need them any longer. When you have cancer, some cells become abnormal. These cells may divide quickly, don't die when they should, and spread into other parts of the body.
Normal breast tissue is made of healthy cells. They reproduce new cells that look and work the same.
Noninvasive breast cancer
(carcinoma in situ) happens when cancer cells are only in the ducts.
Invasive breast cancer happens when cancer cells move out of the ducts or lobules into the surrounding breast tissue.
Metastasis happens when cancer cells move into the lymph nodes or bloodstream and travel to another part of the body.
Several tests are used to measure the size of a tumor and learn how far it has spread. This is called staging. The stage of your cancer will help determine your treatment. Based on National Cancer Institute guidelines, the stages of breast cancer are:
Stage 0. The cancer is noninvasive. Cancer cells are found only in the ducts (ductal carcinoma in situ).
Stage I. The tumor is 2 cm (about 3/4 of an inch) or less in diameter. It has invaded the surrounding breast tissue, and tiny amounts of cancer cells may be found in the underarm lymph nodes.
Stage II. The tumor is larger than 2 cm and has not spread to lymph nodes, or the cancer is less than 5 cm across and has spread to the lymph nodes under the arm.
Stage III. The tumor is less than 5 cm (2 inches) across, and there's a lot of cancer in your underarm lymph nodes, or it has spread to other lymph nodes. Or the tumor is larger than 5 cm and has spread to lymph nodes. Or the tumor is any size and has spread to the skin, chest wall, and maybe to nearby lymph nodes.
Stage IV. The tumor has spread beyond the breast to the bones, lungs, liver, brain, or lymph nodes far away from the breast.
Recurrent breast cancer. When the cancer returns after treatment.
Breast cancer begins in breast tissues. There are two main types of breast cancer, ductal carcinoma and lobular carcinoma.
Gynecologic cancers can include endometrial, ovarian and cervical among others. Some of these cancers are difficult to detect.
Lung cancer is cancer that usually starts in the lining of the bronchi (the main airways of the lungs), but can also begin in other areas of the lungs, including the bronchioles, or alveoli. It is the leading cause of cancer death in both men and women. In 2013, about 228,000 new cases of lung cancer are expected, according to the American Cancer Society.
Lung cancers are believed to develop over a period of many years.
Nearly all lung cancers are carcinomas, a cancer that begins in the lining or covering tissues of an organ. The tumor cells of each type of lung cancer grow and spread differently, and each type requires different treatment.
Lung cancers are generally divided into 2 types:
This type is much more common than small cell lung cancer, accounting for about 85% to 90% of lung cancers. The 3 main kinds of non-small cell lung cancer are named for the type of cells in the tumor:
Squamous cell carcinoma (also called epidermoid carcinoma). It often begins in the bronchi near the middle of the lungs.
Adenocarcinoma. This type usually begins along the outer edges of the lungs. It is the most common type of lung cancer in people who have never smoked.
Large cell carcinomas. These are a group of cancers with large, abnormal-looking cells. These tumors may begin anywhere in the lungs and tend to grow quickly.
This type is sometimes called oat cell cancer because the cancer cells may look like oats when viewed under a microscope, grows rapidly and quickly spreads to other organs. There are two stages of small cell lung cancer:
Limited. In this stage, cancer is generally found in only 1 lung. There may also be cancer in nearby lymph nodes on the same side of the chest.
Extensive. In this stage, cancer has spread beyond the primary tumor in the lung into other parts of the body.
It is important to find out what kind of lung cancer a person has. The different types of carcinomas, involving different regions of the lung, may cause different symptoms and are treated differently.
The following are the most common symptoms for lung cancer. However, each individual may experience symptoms differently.
Lung cancer usually does not cause symptoms when it first develops, but symptoms often become present after the tumor begins growing. A cough is the most common symptom of lung cancer. Other symptoms include:
Constant chest pain
Shortness of breath
Recurring lung infections, such as pneumonia or bronchitis
Bloody or rust-colored sputum
A tumor that presses on large blood vessels near the lung can cause swelling of the neck and face
A tumor that presses on certain nerves near the lung can cause pain and weakness in the shoulder, arm, or hand
Fever for unknown reason
Like many other cancers, lung cancer can cause:
Loss of appetite
Loss of weight
Pain in other parts of the body not affected by the cancer
Other symptoms can be caused by substances made by lung cancer cells, which is referred to as a paraneoplastic syndrome. For example, certain lung cancer cells produce a substance that causes a sharp drop in the level of sodium in the blood, which can cause many symptoms, including confusion and sometimes even coma.
None of these symptoms is a sure sign of lung cancer. Only a doctor can tell whether a patient's symptoms are caused by cancer or by another problem. Consult your doctor for a diagnosis.
A risk factor is anything that increases a person's chance of getting a disease, such as cancer. Different cancers have different risk factors. Several risk factors make a person more likely to develop lung cancer:
Smoking is the leading cause of lung cancer, with about 80% of lung cancer deaths thought to be a result of smoking.
Additional risk factors include:
Secondhand smoke. This refers to breathing in the smoke of others.
Radon. A radioactive gas that cannot been seen, tasted, or smelled. It is produced by the natural breakdown of uranium. High levels of radon may be found in some homes or other buildings, especially basements.
Talc. While no increased risk of lung cancer has been found from the use of cosmetic talcum powder, some studies of talc miners and millers suggest a higher risk of lung cancer and other respiratory diseases from their exposure to industrial-grade talc. Talcum powder is made from talc, a mineral which, in its natural form, may contain asbestos; however, by law, all home-use talcum products (baby, body, and facial powders) have been asbestos-free since 1973.
Cancer-causing agents in the workplace, including:
Radioactive ores, such as uranium
Personal or family history of lung cancer
Air pollution. In some cities, air pollution may slightly increase the risk of lung cancer.
In addition to a complete medical history to check for risk factors and symptoms, and a physical examination to provide other information about signs of lung cancer and other health problems, procedures used to diagnose lung cancer (or to help determine if it has spread) may include:
Chest X-ray. This procedure looks for any mass or spot on the lungs.
Computed tomography scan (also called a CT or CAT scan). A diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs such as the lungs. CT scans are more detailed than general X-rays.
Sputum cytology. A study of phlegm (mucus) cells under a microscope.
Thoracentesis. A hollow needle is inserted through the skin in the chest wall to remove fluid, which is then sent to the lab to be checked for cancer cells.
Needle biopsy. A thin, hollow needle is guided into the mass while the lungs are being viewed on a fluoroscopy or CT scan, and a sample of the mass is removed and evaluated in the pathology laboratory under a microscope.
Bronchoscopy. The examination of the bronchi (the main airways of the lungs) using a flexible tube (bronchoscope) passed down the mouth or nose. Bronchoscopy helps to evaluate and diagnose lung problems, assess blockages, obtain samples of tissue and/or fluid, and/or to help remove a foreign body.
Endobronchial ultrasound. An exam in which a bronchoscope with a small ultrasound transducer on its tip is passed down the windpipe to look at lymph nodes in the mediastinum (the space between the lungs). If enlarged lymph nodes are seen, a small needle can be passed down the bronchoscope and through the wall of the airway to get samples of the nodes for testing.
Mediastinoscopy. A process in which a small cut is made in the neck so that a tissue sample can be taken from the lymph nodes (mediastinal nodes) along the windpipe and the major bronchial tube areas to evaluate under a microscope.
Thoracoscopy. A procedure in which a small cut is made in the side of the chest wall through which a small tube with a video camera on the end is inserted. This allows the doctor to look at the outer part of the lungs and chest wall and to sample any abnormal areas for viewing under a microscope.
MRI, PET, or bone scans. These procedures are done to determine if the cancer has spread from where it started into other areas of the body.
Other tests and procedures may be used as well.
Specific treatment for lung cancer will be determined by your doctor based on:
Your age, overall health, and medical history
The type of lung cancer
Extent of the disease
Your tolerance for specific medications, procedures, or therapies
Expectations for the course of the disease
Your opinion or preference
Depending on its type and stage, lung cancer may be treated with surgery, chemotherapy or other medications, radiation therapy, local treatments such as laser therapy, or a combination of treatments. Combination treatment or multimodality treatment refers to having more than 1 type of treatment.
Treatment for lung cancer includes 1 or more of the following:
Surgery. Surgery is part of the treatment for early stage lung cancers. The type of surgery depends on the size and location of the tumor in the lung, the extent of the cancer, the general health of the patient, and other factors. Many surgeries are done with a long incision in the side of the chest, known as a thoracotomy. Some early stage tumors may be treated with video assisted thoracic surgery (VATS), which uses several small incisions (instead of 1 large one) and special long surgical tools. Types of surgery include:
Segmental or wedge resection. Removal of only a small part of the lung.
Lobectomy. Removal of an entire lobe of the lung.
Pneumonectomy. Removal of an entire lung.
Sleeve resection. Removal of a piece of bronchus, after which the lung is reattached to the remaining part of the bronchus.
Radiation therapy. Radiation therapy is the use of high-energy radiation to kill cancer cells and to shrink tumors. Radiation may also be used with chemotherapy to treat lung cancer. There are 2 ways to deliver radiation therapy:
External radiation (external beam therapy). A treatment that precisely sends high levels of radiation directly to the cancer cells. The machine is controlled by the radiation therapist. Since radiation is used to kill cancer cells and to shrink tumors, special shields may be used to protect the tissue surrounding the treatment area. Radiation treatments are painless and usually last a few minutes.
Internal radiation (brachytherapy, implant radiation). Radiation is given inside the body as close to the cancer as possible. Substances that produce radiation, called radioisotopes, may be swallowed, injected, or implanted directly into the tumor. Some of the radioactive implants are called seeds or capsules. Internal radiation involves giving a higher dose of radiation in a shorter time span than with external radiation. Some internal radiation treatments stay in the body temporarily. Other internal treatments stay in the body permanently, though the radioactive substance loses its radiation within a short period of time. In some cases, both internal and external radiation therapies are used.
Chemotherapy. The use of anticancer drugs to treat cancerous cells. In most cases, chemotherapy works by interfering with the cancer cell's ability to grow or reproduce. Different groups of drugs work in different ways to fight cancer cells. The oncologist will recommend a treatment plan for each individual. Chemotherapy may be given before other treatments, after other treatments, or alone for lung cancer.
Photodynamic therapy (PDT). A type of laser treatment that involves injecting photosensitizing chemicals into the bloodstream. Cells throughout the body absorb the chemicals. The chemicals collect and stay longer in the cancer cells than in the healthy cells. At the right time, when the healthy cells surrounding the tumor may already be relatively free of the chemical, the light of a laser can be focused directly on the tumor. As the cells absorb the light, a chemical reaction destroys the cancer cells. For lung cancer, the light is delivered through a bronchoscope (a small, flexible tube with a light on the end) that is inserted through the mouth or nose.
Targeted therapy. These are drugs that target specific parts of cancer cells or nearby cells that help them grow. So far, these drugs have only been found to be useful for some non-small cell lung cancers. For example, as cancers grow, they form new blood vessels which nourish them. Research aimed at blocking the growth of these blood vessels has led to the development of medications called antiangiogenesis medications. Bevacizumab is 1 of these medications. It has been found to be helpful in prolonging the survival of some patients with advanced lung cancer. It is used with the standard chemotherapy regimen. Medications with other specific targets, such as crizotinib, erlotinib, and cetuximab, may also be useful.
There are specific names for the order in which treatment is given. Neoadjuvant treatment refers to having radiation or chemotherapy before surgery. Having one or both of these before surgery may help shrink the tumor, as a smaller tumor is easier to take out in surgery.
Chemotherapy or radiation soon after surgery is called adjuvant treatment. The goal of adjuvant treatment is to kill any cancer cells that may be left after the surgery. Even if there is no sign of cancer cells, your doctor may suggest adjuvant treatment, as it may lower the risk that the cancer will come back or spread.
Clinical trials are being conducted on prevention and treatment options for lung cancer, including photodynamic therapy and chemoprevention.
There are two types of lung cancer, small cell and non-small cell. Smoking is the leading cause of lung cancer.
Urologic cancers can occur in any organ of the urologic system, including the kidneys, testicles and prostate. Each type of cancer has different symptoms and treatments.
