Stage IV of breast cancer, or the advanced form of breast cancer, is commonly referred to as metastatic breast cancer. Although not a specific type of cancer, it denotes the severity and stage of the progression of the disease. At this stage, the cancer has spread beyond the breast and has affected the lymph nodes associated with other organs in the body, such as the bones, liver, lungs, and even the brain.

Staging in cancer is the process which indicates the extent of damage done by the cancerous cells. It helps the doctors to understand how early or advanced the cancer is. Once diagnosed, the staging of cancer helps doctors to plan the treatment as well as track the patient’s progress during and after the procedures.

Biosimilars are a copy of the original biologic medical product used in the treatment of a particular disease. These are also known as follow-on or subsequent entry biologics. Biosimilars are officially approved versions of the original “innovator” medicines and are manufactured by a different pharmaceutical company. However, biosimilars can be manufactured only after the patent of the original biologic expires.

Cancer that begins to develop in the lymphatic system through the lymphocytes, a type of white blood cell, is known as lymphoma. These cells are an important part of the immune system and work to protect the body against different diseases. As this cancer is present in the lymphocytes, it increases the risk of metastasizing and spreads to the different body parts through the bloodstream.

Crohn’s disease is a chronic inflammatory disease that causes inflammation of the digestive tract, also known as the gastrointestinal tract (GI).

Lung cancer is one of the leading causes of deaths that occur due to cancer. It is estimated that lung cancer causes more deaths than breast, ovarian, and prostate cancers combined. Based on the statistical data by the American Cancer Society, there are about 220,000 new cases of lung cancer every year.
