Types of Cancer (A-H)

Learn more about different types of cancer here in this detailed list of various cancers.

1. Anal Cancer. Anal cancer is cancer that develops in the anus, the opening of the rectum, which allows waste to pass from the large intestine to outside of the body. The anus is often confused with the rectum, which is the last several inches of the lower intestine. The rectum ultimately ends at the anus, where fecal material exits the body.

2. Bladder Cancer. Bladder cancer is a disease that affects the bladder, an elastic organ that is responsible for storing urine that is released by the kidneys. It is the fifth most common type of cancer in the U.S. and when diagnosed in the early stages, it is highly treatable.

There are several types of bladder cancer, some being more common than others. The most common type of bladder cancer is urothelial carcinoma, accounting for about 90% of bladder cancer cases. The remaining types of bladder cancer are considered rare. They include squamous cell carcinoma, adenocarcinoma, small cell carcinoma, leiomyosarcoma, lymphoma, and, melanoma.

3. Brain Tumors. Brain tumors are the result of uncontrolled growth of abnormal cells in the brain. They can affect children and adults, but are considered to be rare among both populations. Brain tumors can be classified as malignant (cancerous) or benign (non-cancerous). Malignant tumors tend to be more aggressive than benign types, but both are very serious and can be fatal.

There are over 140 different types of brain tumors that can form in the brain. Brain tumors can be classified as primary or metastatic, depending on where they arise in the body. Primary brain tumors originate in the brain and rarely spread outside of it. Metastatic tumors begin in another part of the body and spread to the brain through blood or lymphatic tissue. Some cancer types are more prone to spreading to the brain. These types include breast cancer, kidney cancer, melanoma, and lung cancer.

4. Breast Cancer. Breast cancer is a type of cancer that occurs when a malignant tumor forms from cells within the breast. It occurs most frequently in women, however, men can develop breast cancer, although much less frequently. The American Cancer Society estimates that 1 in every 8 women will develop breast cancer in their lifetime, making it the most common cancer among women, aside from skin cancer.

5. Cervical Cancer. Cervical cancer is malignant neoplasm of the cervix uteri or cervical area. One of the most common symptoms is abnormal vaginal bleeding, but in some cases there may be no obvious symptoms until the cancer is in its advanced stages

6. Colon/ Colorectal Cancer. Rectal cancer is a type of cancer that develops in the rectum, the bottom portion of the colon (large intestine) closest to the anus. Like other organs in our body, the rectum is vulnerable to many diseases and conditions, including cancer.

In the early stages, a patient with rectal cancer may not have symptoms. With advanced disease, more symptoms may appear. Every patient is different.

7. Endometrial Cancer. Endometrial cancer is a type of cancer that develops in the endometrium, the lining of the uterus in women. It is commonly referred to as uterine cancer, but other types of cancer do develop in the uterus, though much less often.

Endometrial cancer is most often diagnosed in women who went through menopause but can be diagnosed in younger women too. It is most often found in the early stages, when the disease is most treatable.

8. Esophageal Cancer. Esophageal cancer develops in the esophagus, a long tube that connects your mouth to your stomach. It is generally hollow and is about ten inches long in adults. Esophageal cancer is also referred to as cancer of the esophagus.

9. Gallbladder Cancer. Gallbladder cancer is a disease that affects the gallbladder. The gallbladder is an organ located in the abdomen that is responsible for storing bile. It is pear shaped and about 4 inched in length and about 1 inch wide.

Gallbladder cancer usually does not exhibit symptoms until the disease has advanced.

10. Head and Neck Cancer. Head and neck cancer is cancer that originates in the head or neck region, not including thyroid or skin cancers. Several types of cancer are considered head and neck cancer:
     • oral cancer
     • salivary gland cancer
     • laryngeal cancer
     • hypopharyngeal tumors
     • nasopharyngeal cancer
     • tumors of the oropharynx
     • tumors of the nasal cavity and paranasal sinuses
