Breast cancer – Signs, Symptoms and causes.
Breast cancer is a type of cancer that starts in the cells of the breast. It is the most common cancer in women worldwide, but it can also occur in men. Here are some symptoms and causes of breast cancer:
- A lump or thickening in the breast or underarm area
- Swelling or redness of the breast
- Changes in the size or shape of the breast
- Nipple discharge, other than breast milk
- Nipple changes, such as inversion (turning inward)
- Skin changes, such as dimpling, puckering, or scaling
- Breast pain that does not go away after the menstrual cycle
The exact cause of breast cancer is unknown, but several factors can increase the risk of developing it, including:
- Age: Breast cancer is more common in women over 50 years old.
- Gender: Women are more likely to develop breast cancer than men.
- Family history: A history of breast cancer in close relatives, especially mother, sister, or daughter, can increase the risk of developing it.
- Genetics: Some genetic mutations, such as BRCA1 and BRCA2, increase the risk of breast cancer.
- Hormonal factors: Excessive exposure to estrogen and progesterone, such as in early menstruation, late menopause, or hormone replacement therapy, can increase the risk of breast cancer.
- Lifestyle factors: Smoking, alcohol consumption, obesity, and a lack of physical activity can increase the risk of breast cancer.
It is important to remember that not all breast lumps are cancerous, and many breast cancers are found by routine screening before they cause any symptoms. If you notice any changes in your breast, talk to your doctor. Early detection and treatment can improve the chances of survival.
