Most types of cancer form a tumor, a lump or mass of cancerous cells. Cells from a tumor may break away and travel to other parts of the body, where they can settle and multiply. This spreading process is called metastasis. New cancers that have broken off and spread from the original...

In his groundbreaking 1971 article, Judah Folkman introduced the idea of a "diffusible message" released from solid tumor cells to invoke a robust capillary-sprouting response, more robust than ordinary wound healing or inflammation, to help support its cancerous growth. In the same light, Folkman...
These abnormal cells are termed cancer cells, malignant cells, or tumor cells. These cells can infiltrate normal body tissues. Cancer is the uncontrolled growth of abnormal cells anywhere in a body. These abnormal cells are termed cancer cells, malignant cells, or tumor cells. These cells can...
Yes, doctors define mesothelioma as a cancer. It’s classified as malignant (cancerous) because it can invade nearby tissues and spread to other parts of the body, a process known as metastasis. Mesothelioma begins in the mesothelium, the thin layer of tissue that lines and protects internal...
a patient is diagnosed before the cancer has spread or elects to undergo treatment to combat the cancer, their prognosis may improve. Factors that may influence prognosis include: the stage of a patient’s mesothelioma at the time of diagnosis, type of mesothelioma, size of the tumor, ...
There are many risk factors that increase the chance of developing breast cancer. Although we know some of these risk factors, we don't know the cause of breast cancer or how these factors cause the development of a cancer cell. We know that normal breast cells become cancerous because of...
