About ovarian cancer?

Cancer is the name for a group of diseases that develop when the body’s cells grow in an uncontrolled way and spread into the body’s tissues. Ovarian cancer is cancer that affects the ovaries.When cells grow in an uncontrolled way and spread into the body’s tissues, this is called invasive cancer. The site where the cancer starts is called the primary cancer.

Sometimes ovarian cancer cells travel in the bloodstream or lymphatic system to other parts of the pelvis, or to areas outside the pelvis such as the lungs or liver. This is called advanced ovarian cancer (or metastatic ovarian cancer).

About the ovaries

Women usually have two ovaries, one on each side of the uterus (womb). The ovaries are linked to the womb by two tubes called the fallopian tubes. The outer covering of the ovaries is called the epithelium (skin). Inside the ovaries are cells that release female hormones and cells that will mature into eggs.

The lymphatic system

The lymphatic system is a network of tiny vessels that collect fluid and waste products from the body’s tissues. This fluid is called lymph.

The lymphatic vessels take the lymph to small glands called lymph nodes where substances that could be harmful to the body, such as bacteria or cancer cells, are trapped and removed. This helps to protect the body from infection. The lymph then passes back into the blood.

Lymph nodes are small, rounded glands that can range in size from about 1 mm to
25 mm.

There are lymph nodes all around the body, including the armpit, groin, stomach, chest and neck. The number of lymph nodes varies in different people.
