Mucinous carcinoma of the ovary is a type of ovarian cancer that develops from cells that produce mucus. Under the microscope, the tumor cells resemble the cells that line parts of the digestive tract, such as the stomach or intestines, which is why pathologists describe this tumor as having “mucinous” or gastrointestinal-type features. Mucinous carcinoma …

Low-grade serous carcinoma of the ovary is a type of ovarian cancer that develops from cells similar to those lining the fallopian tube. It is called “low grade” because the tumor cells look less abnormal under the microscope and tend to grow more slowly than those seen in high-grade serous carcinoma. Low-grade serous carcinoma accounts …

High-grade serous carcinoma of the ovary is the most common type of ovarian cancer. It develops from epithelial cells that closely resemble the cells lining the inside of the fallopian tube. High-grade serous carcinoma accounts for about 70% of all ovarian carcinomas, and many cases are diagnosed after the cancer has already spread within the …

Adenocarcinoma of the esophagus is a type of cancer that develops from gland-forming cells in the esophagus’s lining. It almost always starts in the lower part of the esophagus, near where it joins the stomach — an area called the esophagogastric junction. In some cases, it extends into the uppermost part of the stomach. This …

HPV-associated adenocarcinoma is a type of cervical cancer that develops from the glandular cells lining the inside of the cervix. These cells normally produce mucus and form the lining of the cervical canal, the passageway connecting the uterus to the vagina. HPV-associated adenocarcinoma is caused by persistent infection with high-risk human papillomavirus (HPV) types, particularly HPV18, …

Ductal carcinoma in situ (DCIS) is a noninvasive type of breast cancer that starts in the lining of the breast ducts — the tiny tubes that carry milk from the glands to the nipple. Noninvasive means that all the abnormal cells are confined inside the ducts and have not broken through the duct wall into …

Prostatic adenocarcinoma is the most common type of prostate cancer. It is sometimes called acinar adenocarcinoma because the cancer cells form small clusters that resemble glands called acini. The cancer develops from epithelial cells that normally line the inside of the prostate gland. Prostate cancer is one of the most common cancers in men, …

Mantle cell lymphoma is a type of blood cancer that starts in B cells — the white blood cells that help the body fight infections by producing antibodies. It takes its name from the mantle zone, a ring of B cells that normally surrounds the germinal center within a lymph node, and it is from …

Hodgkin lymphoma is a type of cancer that starts in the immune system, most often in the lymph nodes — the small, bean-shaped glands distributed throughout the body that filter lymph fluid and house immune cells. It is defined by the presence of specific abnormal cells called Reed-Sternberg cells, which can be identified under the …

Follicular lymphoma is a group of closely related blood cancers that start in B cells — specialized white blood cells that normally help the body fight infection. These cancers are called “follicular” because the abnormal cells grow in round clusters called follicles, resembling the normal structures found inside healthy lymph nodes. Follicular lymphoma is the …
