LESSON 14.3 “Cancer”

Cancer: a group of diseases in which cells divide in an uncontrolled manner. Not contagious Not caused by injury Causes are not completely understood, we do understand risk factors Cancer can be prevented

Carcinogens: chemical that is known to cause cancer.

What is cancer? (Video)

Tumor: an abnormal growth Benign tumor: non-cancerous tumor Malignant tumor: cancerous tumor Metastasis: the spread of cancer.

Spread of Cancer (Video)

Benign Tumor: non-cancerous

Malignant Tumor: cancerous tumor

Malignant vs. Benign MalignantBenign

Treatments Radiation Therapy: high-energy radiation Chemotherapy: anti-cancer drugs Immunotherapy: immune system is stimulated to fight cancer.
