 What is cancer and it's symptoms.

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body. These abnormal cells can form tumors and can also invade nearby parts of the body, as well as spread to distant organs through the bloodstream and lymphatic system. There are many different types of cancer, and they can occur in any part of the body. Some of the most common types include breast cancer, lung cancer, prostate cancer, and colon cancer. Risk factors for cancer include genetics, lifestyle factors such as smoking and excessive alcohol consumption, exposure to certain chemicals and substances, and certain viral infections.

The symptoms of cancer can vary depending on the type and stage of the disease, as well as the location of the tumor(s) in the body. Some common symptoms of cancer include:

1. Fatigue

2. Pain

3. Weight loss or loss of appetite

4. Lumps or masses that can be felt under the skin

5. Changes in the skin, such as a new mole or a change in an existing mole

6. Changes in the mouth, such as sores that don't heal or white patches on the tongue or gums

7. Persistent cough or hoarseness

8. Shortness of breath

9. Blood in the urine or stool

10. Persistent fatigue or weakness

It's important to note that many of these symptoms can also be caused by other, non-cancerous conditions, so it's essential to see a doctor if you have any symptoms that concern you. A combination of physical exam, imaging tests, and biopsy are needed to confirm the diagnosis.

It's worth noting that some types of cancer may not produce any symptoms in the early stages, and may only be found on routine cancer screening or in an advanced stage.
