Breast cancer is a type of cancer that develops in the breast cells, predominantly affecting females. It is the most common cancer among women worldwide. Breast cancer can occur in both men and women, but it is about 100 times more common in females.

Causes:

The exact causes of breast cancer are not fully understood, but certain risk factors can increase a woman’s likelihood of developing the disease. These risk factors include:

Age: The risk of breast cancer increases with age, particularly after menopause.

Family history: Having a close relative, such as a mother or sister, with breast cancer increases the risk.

Genetic factors: Mutations in certain genes, such as BRCA1 and BRCA2, can significantly increase the risk of breast cancer.

Hormonal factors: Prolonged exposure to estrogen, including early onset of menstruation, late menopause, and never having been pregnant, can increase the risk.

Lifestyle factors: Obesity, excessive alcohol consumption, and a sedentary lifestyle may contribute to an increased risk.

Symptoms:

Common symptoms of breast cancer include:

A lump or thickening in the breast or armpit.

Changes in breast size or shape.

Dimpling or puckering of the breast skin.

Nipple changes, such as inversion, redness, or discharge.

Swelling or lump in the lymph nodes under the arm.

It’s important to note that not all breast lumps are cancerous, and many breast changes are benign. However, if you notice any changes or abnormalities in your breasts, it’s essential to consult a healthcare professional for further evaluation.
