Cancer is a group of diseases characterized by uncontrolled cell growth, invasion, and metastasis.
Types of Cancer:
1. Carcinomas (breast, lung, colon)
2. Sarcomas (bone, soft tissue)
3. Leukemias (blood)
4. Lymphomas (lymphatic system)
5. Melanomas (skin)
6. Brain and spinal cord tumors
7. Gynecologic cancers (cervical, ovarian)
8. Prostate cancer
9. Pancreatic cancer
10. Liver cancer
*Causes and Risk Factors:*
1. Genetics
2. Environmental factors (radiation, chemicals)
3. Viral infections (HPV, HIV)
4. Family history
5. Age
6. Smoking
7. Obesity
8. Physical inactivity
9. Diet (processed meat, low fiber)
10. Radiation exposure
*Symptoms:*

6. Difficulty swallowing
7. Changes in bowel habits
8. Urinary problems
9. Lumps or thickening
10. Abnormal bleeding
*Diagnosis:*
