actinic keratosis Sun-Damaged Skin Although most people love the warmth and light of the sun, too much sun exposure can significantly damage human skin. breast Breast Cancer Breast cancer is a type of uncontrolled growth of abnormal cells that can develop in one of several areas of the breast, including: the ducts that carry milk to the nipple, the breast's lobules (small sacs that produce milk) or the breast's nonglandular tissue. cervical Cervical Cancer Cervical cancer begins with abnormal, microscopic changes in cells in the outer layer of the cervix, called the epithelium. esophageal Esophageal Cancer Esophageal cancer is the abnormal growth of cells in the esophagus, the tube that carries food and drink from your throat to your stomach. gallbladder and bile duct Gallbladder and Bile Duct Cancer The gallbladder is a small, pear-shaped pouch that lies beneath the liver, in the upper abdomen. It stores bile. This fluid, produced by the liver, helps digest fat. The gallbladder releases bile into the small intestine through the bile duct. This thin tube connects the liver and gallbladder to the small intestine. Cancer develops when abnormal cells in these structures multiply and grow rapidly. melanoma (mole cancer) Melanoma Melanoma is cancer of the cells that give skin its color. oral cavity Oral Cancer Oral cancer is cancer anywhere in the front of the mouth.

Like other parts of the body, the salivary glands can develop infections, tumors, inflammations, malfunctions and other problems. stomach Stomach Cancer Stomach cancer, also called gastric cancer, is the uncontrolled growth of abnormal cells that form the inner lining of the stomach. testicles Testicular Cancer Testicular cancer is the uncontrolled growth of abnormal cells in one or both testicles (testes). throat Throat Cancer (Larynx and Pharynx) Throat cancer occurs when cells in the organs used for breathing, speaking, and swallowing begin to divide rapidly and abnormally. uterine Uterine Cancer Uterine cancer is the most common cancer of the female reproductive tract. There are two main types: endometrial cancer and uterine sarcoma. vaginal Vaginal Cancer Vaginal cancer is the uncontrolled growth of abnormal cells in the vagina (birth canal). vulvar Vulvar Cancer Vulvar cancer occurs in the vulva, the external genital area of a woman's reproductive system. basal cell carcinoma Basal Cell Carcinoma Basal cell cancer is the most common form of skin cancer diagnosed in the United States. Basal cells are small, round skin cells normally found in the upper part of your skin. Kaposi's sarcoma Kaposi's Sarcoma Kaposi's sarcoma is a type of cancer caused by the virus human herpes virus 8. The tumors appear as red or purple patches on the skin, mouth, lungs, liver, or gastrointestinal tract. lymphoma Lymphoma (Hodgkin Disease and Non-Hodgkin Lymphoma) Lymphoma is a cancer of the lymph (or lymphatic) system. It is part of the immune system. It collects and destroys invading organisms, such as bacteria and viruses, and abnormal cells. leukemia Leukemia Leukemia is a form of cancer that affects the body's ability to make healthy blood cells. multiple myeloma Multiple Myeloma Multiple myeloma is cancer of the bone marrow caused by the uncontrolled growth of plasma cells. These cells are one type of white blood cells. lung (overview) Lung Cancer One of the most common cancers, lung cancer usually occurs when a cancer-causing agent, or carcinogen, triggers the growth of abnormal cells in the lung. adenocarcinoma Adenocarcinoma of the Lung Like other cancers, adenocarcinoma is the growth of abnormal cells. kidney Kidney Cancer Kidney cancer occurs when abnormal kidney cells grow and divide uncontrollably. The cells invade and destroy the normal kidney tissue, and they can spread (metastasize) to other organs. bladder Bladder Cancer This type of cancer occurs in the bladder - the organ that stores urine. The bladder has an inner lining surrounded by a layer of muscle. Bladder cancer begins in the inner lining of the bladder. It is usually discovered before it has spread past this lining lung, squamous cell Squamous Cell Carcinoma of the Lung Lung cancer (or carcinoma) is one of the most common cancers diagnosed in both men and women. lung, large cell Large Cell Cancer of the Lung Large cell cancer is a type of non-small cell lung cancer. Large cell lung cancers tend to grow quickly and spread. fallopian tube Fallopian Tube Cancer The fallopian tubes connect the ovaries and the uterus. Fallopian tube cancer occurs when cells in a tube multiply out of control and form a tumor. lung, carcinoid tumors Carcinoid Tumors of the Lung Carcinoid tumors have been called "cancers in slow motion." They grow slowly and are less likely than other tumors to spread (metastasize) to other parts of the body. lung, small cell Small Cell Lung Cancer Small cell cancer is a type of lung cancer. Small cell lung cancer has been called oat cell cancer because the cells resemble oats when seen under a microscope. thyroid Thyroid Cancer Thyroid cancer is the uncontrolled growth of abnormal cells in the thyroid gland. The thyroid gland is shaped like a butterfly. It is located under the Adam's apple in the front of the neck. Most cases of thyroid cancer can be cured. head and neck Head and Neck Cancer Head and neck cancer begins with the abnormal growth of cells. These cells multiply out of control, eventually forming a tumor in part of the head or neck. parathyroid Parathyroid Cancer Parathyroid cancer is a very rare cancer that develops in the parathyroid glands. A pair of these pea-sized glands sits next to the thyroid on either side of the front of the neck. Ewing's sarcoma Ewing's Sarcoma Ewing's sarcoma is a very rare cancer that appears as a solid tumor, most often in children and teens. Wilms' tumor Wilms' Tumor Wilms' tumor, also called nephroblastoma, is the most common form of kidney cancer in children. It develops when cancerous kidney cells multiply out of control, eventually forming a mass. osteosarcoma Osteosarcoma Osteosarcoma is the uncontrolled growth of abnormal cells in bone. extragonadal germ cell tumors Extragonadal Germ Cell Tumors Extragonadal germ cell tumors typically form in the chest, lower back and head. lung, malignant mesothelioma Malignant Mesothelioma Malignant mesothelioma is a rare form of cancer that affects the thin membranes that line most of the body's organs. pituitary tumors Pituitary Tumors When tumors develop within the pituitary gland, they are usually small, well-localized, slow-growing masses that arise from one specific family of hormone-producing pituitary cells. immunotherapy Immunotherapy Immunotherapy refers to treatments that stimulate, enhance or suppress the body's own immune system. radiation therapy Radiation Therapy Radiation therapy is a form of cancer treatment that uses ionizing radiation (an intense form of energy) to damage or destroy cancer cells. chemotherapy Chemotherapy Chemotherapy drugs kill cancer cells or prevent them from growing and dividing. Chemotherapy drugs are also called anti-cancer drugs. squamous cell Squamous Cell Carcinoma of the Skin Squamous cells are small, flat skin cells in the outer layer of skin. When these cells become cancerous, they typically develop into flat or raised, rounded skin tumors. Sometimes the skin around the tumors gets red and swollen. neuroblastoma Neuroblastoma Neuroblastoma is a cancer that starts in primitive nerve cells. It affects infants (younger than a year old) and children. rhabdomyosarcoma Rhabdomyosarcoma Rhabdomyosarcoma is a cancer that forms in the skeletal muscles. Skeletal muscles attach to bones. Most rhabdomyosarcomas occur in children and teenagers. choroidal melanoma Choroidal Melanoma Choroidal melanoma is a cancer that affects part of the eye. It develops in the choroid, the sponge-like membrane at the back of the eye between the sclera (the white of the eye) and the retina. retinoblastoma Retinoblastoma Retinoblastoma is a form of cancer that develops on the retina. Although rare, retinoblastoma is the most common eye tumor in children. liver Liver Cancer Liver cancer is the uncontrolled growth of abnormal cells in the liver. soft tissue sarcoma Soft Tissue Sarcoma Soft tissue sarcomas are cancerous tumors that start in either of two types of primitive (immature) cells: nerve cells and mesenchymal cells. biopsy Biopsy A biopsy is a procedure that samples a small amount of tissue or cells for examination in a laboratory. bone marrow transplant Bone Marrow Transplant A bone marrow transplant is a procedure used to treat certain types of cancer and some other diseases. brain tumor Brain Tumor Overview A brain tumor is a mass of abnormally growing cells in the brain or skull. gastric Stomach Cancer Stomach cancer, also called gastric cancer, is the uncontrolled growth of abnormal cells that form the inner lining of the stomach. nephroblastoma Wilms' Tumor Wilms' tumor, also called nephroblastoma, is the most common form of kidney cancer in children.
