HEED-110 Lecture Notes - Lecture 8: Prostate Cancer, Testicular Cancer, Cervical Cancer
Document Summary
Smoking is the primary risk factor for lung cancer. There are more cases of prostate cancer, but lung cancer kills about 3 times as many men as prostate cancer does each year. Testicular cancer is the most common cancer in men under age 30. The primary cause of cervical cancer is infection with human papillomavirus (hpv), a sexyally transmitted pathogen. Chilli peppers, oranges, broccoli help prevent cancer. Cancer is a group of diseases characterized by uncontrolled, disorderly cell growth: primary where the original growth occurs (metastasis, secondary where the cancer has metastasized (spread) Sometimes the nucleus of a cell looses the ability to regulate cell growth, producing a mutant cell. A mass of mutant cells is called a neoplasm (tumor: a neoplasm can be malignant (cancerous) or benign (noncancerous) Malignant tumors can spread and crowd out normal tissue. **metastasis is the process by which cancer cells spread from their primary site to a secondary site**
