Cancer

A type of cancerous (malignant) brain tumor that begins to develop near the brainstem in the cerebellum is called medulloblastoma. It is a fast-growing tumor that can easily spread to other parts of the brain and spinal cord. Commonly, medulloblastoma affects children. Doctors often prescribe surgery, radiation therapy, and chemotherapy to treat this type of […]

A group of tumors that include thymomas, lymphomas, germ cell tumors, and cysts is called mediastinal tumors. These abnormal cells often appear in the space between the lungs (the mediastinum). While some of these tumors are benign (noncancerous), some people may develop malignant (cancerous) tumors. The primary treatment for people who develop mediastinal tumors is […]

A type of lung cancer that occurs when normal cells in the lungs develop DNA mutations (changes) and begin to grow and multiply uncontrollably is called non-small cell lung cancer (NSCLC). Moreover, it is the most common form of lung cancer, and it often grows slowly compared to small-cell lung cancer. However, it can spread […]

A type of blood cancer that develops in the lymphatic system is called non-Hodgkin lymphoma (NHL). These cancerous cells begin to develop in B-cell and T-cell lymphomas. In most cases, the tumor begins to develop in the lymph nodes, but can spread to the lymphatic system or other organs in the body. While some types […]

A group of slow-growing types of B-cell non-Hodgkin lymphoma is called marginal zone lymphoma (MZL). This type of cancer develops in the B lymphocytes (a type of white blood cell). In general, there are several types of MZL, but all of them begin to develop in lymphoid tissue, including the skin, lymph nodes, and spleen. […]

A type of blood cancer that begins to develop in the white blood cells in the lymph nodes (lymphocytes) is called mantle cell lymphoma (MCL). A lot of people who develop this type of blood cancer experience a cycle of remission and relapse. It means the symptoms disappear for a short period and then return. […]

A rare form of non-Hodgkin lymphoma that develops in the lining of the abdomen (gastric MALT) is called MALT lymphoma. Sometimes, it is called extranodal marginal zone lymphoma, and it may also develop in the lungs, skin, thyroid, salivary gland, or near the eye (non-gastric MALT). While doctors can put this type of cancer in […]

A form of abnormal growth that often affects people under 30 and develops in the reproductive cells (also called germ cells) inside the ovaries is called ovarian germ cell tumors. While most of these growths are benign (noncancerous), sometimes they may be malignant (cancerous). Most of the time, these growths are treated with surgery, but […]

The tumors that begin to develop in the tissues that surround and support nerve cells are called nerve sheath tumors. While most of them are benign (noncancerous), in rare cases, some of them can become malignant (cancerous). Usually, noncancerous tumors are removed with surgery, and they do not return after treatment. Neurofibromas, schwannomas, and malignant […]

A rare genetic condition in which people experience benign (noncancerous) tumors in cartilage (enchondromas), often in the hands, is called Maffucci syndrome. People with this syndrome often experience bone pain, skeletal abnormalities, and have an increased risk of fractures. Sometimes, it may also involve abnormal tangles of blood vessels on the skin (also called hemangiomas). […]
