Overview
Breast cancer occurs when cells within the breast tissue divide and mutate rapidly, forming a tumour that can spread to other parts of the body.
It is the most common type of cancer detected in women. Breast cancer doesn’t just affect women—understanding its causes, symptoms, and prevention methods is crucial.
Risk Factors of Breast Cancer
Cancer is a complex disease that can have various causes. Several risk factors contribute to the development of breast cancer, including:
- Genetic Makeup: Mutations in genes like BRCA1 and BRCA2 increase the risk.
- Obesity: Being overweight significantly raises the risk.
- Early Periods: Starting menstruation before age 12 can increase risk.
- Late Menopause: Women with later menopause are at higher risk.
- Hormone Therapy Medications: Used to treat menopause symptoms but can elevate cancer risk.
- Dense Breast Tissue: Makes tumour detection harder during mammograms.
- Radiation Exposure: Prolonged exposure increases the chance of mutations.
Breast Cancer Symptoms
Symptoms can resemble other conditions but should never be ignored. Common signs include:
- Lump in the breast
- Change in nipple colour or inverted nipple
- Skin irritation or dimpling
- Lump in underarm areas
- Blood or white discharge from nipples
- Change in skin colour of the breast
- Itching or scaling of nipple or breast skin
Causes of Breast Cancer
The exact causes are not known, but researchers have identified several risk-enhancing factors, including genetics, hormones, lifestyle, and environmental exposure.
Cancer occurs when the genetic makeup of your cells changes, leading to uncontrolled cell growth.
Prevention of Breast Cancer
No one can completely prevent cancer, but healthy habits can significantly lower risk. Steps include:
- Avoid birth control pills after age 35
- Avoid post-menopausal hormones
- Timely screening and mammography
- Quit smoking
- Eat a nutritious diet and avoid alcohol
- Maintain a healthy weight and exercise regularly
Diagnosis
Breast cancer diagnosis involves imaging tests, biopsies, and genetic testing. Early detection dramatically improves treatment outcomes.
- Breast Exam: Physical examination for lumps or abnormalities.
- Mammogram: X-ray imaging to detect early-stage breast cancer.
- Breast Ultrasound: Differentiates between solid and fluid-filled lumps.
- Biopsy: Tissue sampling from suspicious areas for laboratory testing.
Treatment Options for Breast Cancer
1. Surgery
Involves removing the tumour through breast-conserving surgery or mastectomy, depending on the case.
2. Chemotherapy
Uses drugs to kill or stop the growth of cancer cells, delivered orally or intravenously.
3. Hormone Therapy
Blocks hormones that promote cancer growth by reducing or stopping their effects.
4. Targeted Therapy
Uses precision drugs that specifically target cancer cells with minimal harm to healthy tissue.
5. Immunotherapy
Boosts the body’s immune system to identify and attack cancer cells effectively.
6. Radiation Therapy
Employs high-energy X-rays to kill or slow down the growth of cancer cells.
Takeaway
Breast cancer is one of the most treatable cancers if detected early. Awareness, timely screening, and lifestyle changes are key to prevention and survival.
Regular self-exams and medical consultations empower individuals to take control of their breast health and ensure timely care.
