What is Cancer?
Cancer is uncontrolled cell growth which is caused by mutations in genes regulating the cell cycle, this is called a tumor. These tumors come in different stages, some being more crucial than others. Tumors can be either or benign or malignant. Malignant tumors are seriously cancerous and highly capable of spreading while benign tumors are less cancerous and more localized.
Malignant Tumors are extremely invasive, so they can invade nearby tissues and metastasize, this means they spread around your body through your bloodstream or lymphatic system. In order to determine wether a tumor is benign or malignant a biopsy is preformed. A biopsy is where a doctor examines a piece of tissue to decide what type and stage the cancer is.

Tumor Suppressor Genes:
Tumor Suppressor Genes:
When inactivated these fail to stop irregular cell division. An example of this is p53 mutation.
