Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. If left untreated, these abnormal cells can spread to other parts of the body and damage healthy tissue. There are many different types of cancer, and they can develop in almost any part of the body.

COMMON TYPES OF CANCER

• Breast Cancer.
• Kidney Cancer.
• Lung Cancer .
• Oral Cancer.

1. BREAST CANCER

       Breast cancer is a type of cancer that affects the cells in the breast. It is the most common cancer in women, although it can also occur in men.

There are several risk factors for breast cancer, including:

• Being a woman (breast cancer is more common in women than in men)
• Age (risk increases as you get older)
• Personal or family history of breast cancer
• Genetic mutations, such as BRCA1 and BRCA2
• Early onset of menstruation (before age 12)
• Late menopause (after age 55)
• Never having children or having children after age 30
• Using hormone replacement therapy (HRT) after menopause
• Alcohol consumption
• Obesity
• Lack of physical activity

There are several ways to reduce the risk of breast cancer:

• Maintain a healthy weight
• Exercise regularly
• Limit alcohol consumption
• Breastfeed, if possible
• Avoid HRT, or use it at the lowest dose for the shortest possible time

2. KIDNEY CANCER

    Kidney cancer is a type of cancer that affects the kidneys, which are a pair of bean-shaped organs located in the back of the abdomen. The kidneys are responsible for filtering waste and excess fluids from the blood, and they also help regulate blood pressure and produce hormones.

Some risk factors for kidney cancer include:

• Smoking
• Obesity
• High blood pressure
• Long-term dialysis
• Certain inherited conditions, such as von Hippel-Lindau disease and hereditary papillary renal cell carcinoma
• Certain occupational exposures, such as working with certain chemicals or metals

3. LUNG CANCER

Lung cancer is a type of cancer that affects the lungs, which are a pair of organs in the chest that are responsible for exchanging oxygen and carbon dioxide in the blood. There are two main types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most common type, accounting for about 80-85% of all cases.

The main cause of lung cancer is tobacco smoking, and the risk of developing lung cancer increases with the amount of tobacco smoked and the length of time a person has smoked. Other risk factors for lung cancer include exposure to secondhand smoke, exposure to certain chemicals and substances, such as asbestos and radon, and a family history of lung cancer.

4.ORAL CANCER

Oral cancer is a type of cancer that affects the mouth, including the lips, tongue, gums, and the inside of the cheeks. It can also affect the back of the throat, including the tonsils and the base of the tongue.

The main risk factor for oral cancer is tobacco use, including smoking and chewing tobacco. Other risk factors include heavy alcohol consumption, exposure to sunlight (which can increase the risk of lip cancer), and a diet low in fruits and vegetables. Some people are also at increased risk due to certain genetic factors.
