Breast Cancer

What is Breast Cancer?

Breast cancer is a type of cancer that forms in the cells of the breast tissue. It is the most common cancer among women worldwide, although it can also occur in men. Breast cancer usually begins in the ducts (ductal carcinoma) or lobules (lobular carcinoma) of the breast, but it can also occur in other areas of the breast tissue.

Risk factors

  1. Gender: Women are much more likely to develop breast cancer than men.

  2. Age: The risk of breast cancer increases with age, with the majority of cases occurring in women over the age of 50.

  3. Family history: A personal or family history of breast cancer or certain genetic mutations (such as BRCA1 and BRCA2) can increase the risk.

  4. Reproductive factors: Early menstruation (before age 12), late menopause (after age 55), late age at first childbirth, and never having children may increase the risk.

  5. Hormone replacement therapy: Long-term use of hormone replacement therapy (HRT) after menopause may increase the risk.

  6. Personal history of breast cancer or certain non-cancerous breast conditions (such as atypical hyperplasia or lobular carcinoma in situ)

  7. Dense breast tissue: Women with dense breast tissue on mammograms may have an increased risk.

  8. Radiation exposure: Previous radiation therapy to the chest or breasts, particularly at a young age, may increase the risk.

  9. Lifestyle factors: Factors such as obesity, physical inactivity, alcohol consumption, and smoking may increase the risk.


Symptoms of breast cancer include:

  • A lump or mass in the breast or underarm area

  • Changes in breast size, shape, or texture

  • Breast pain or tenderness

  • Nipple discharge, particularly if bloody

  • Changes in the appearance of the nipple or breast skin, such as redness, dimpling, or puckering

Treatment options

Treatment for breast cancer depends on various factors, including the type and stage of the cancer, the size and location of the tumor, and the individual's overall health and preferences. Treatment options may include surgery (such as lumpectomy or mastectomy), radiation therapy, chemotherapy, hormone therapy, targeted therapy, or immunotherapy. The choice of treatment is often made in consultation with a multidisciplinary team of healthcare providers, including surgeons, oncologists, radiation therapists, and other specialists, to provide comprehensive care tailored to the individual's needs.


Early detection and comprehensive treatment are crucial for improving outcomes and increasing survival rates for individuals diagnosed with breast cancer. Regular breast cancer screening, including mammograms and clinical breast exams, can help detect breast cancer at an early stage when it is most treatable. Additionally, lifestyle modifications such as maintaining a healthy weight, being physically active, limiting alcohol consumption, and avoiding smoking may help reduce the risk of developing breast cancer.

Can exercise help?

Exercise can play a significant role in managing breast cancer by: 

  1. Improving physical function: Regular exercise helps to maintain or improve physical function, strength, and endurance, which can be particularly important for individuals undergoing breast cancer treatment, such as surgery, chemotherapy, or radiation therapy, which may cause fatigue and loss of muscle mass.

  2. Reduce treatment side effects: Exercise can help to alleviate common side effects of breast cancer treatment, such as fatigue, muscle weakness, joint pain, and lymphedema (swelling of the arm), by improving overall physical fitness and reducing inflammation.

  3. Enhance quality of life: Regular exercise has been shown to improve overall quality of life, increase energy levels, reduce anxiety and depression, and promote a sense of well-being and empowerment, despite the challenges of living with breast cancer.

  4. Promote cardiovascular health: Aerobic exercise helps to improve cardiovascular fitness, lower blood pressure, and reduce the risk of heart disease, which is important for overall health and well-being in individuals with breast cancer.

  5. Facilitate weight management: Regular physical activity helps to control body weight and reduce excess body fat, which may be beneficial for individuals with breast cancer, as obesity and excess body fat have been associated with an increased risk of cancer recurrence and poorer outcomes.

  6. Reduce risk of cancer recurrence: Some research suggests that regular exercise may help to reduce the risk of cancer recurrence and improve survival rates in individuals with breast cancer by reducing inflammation, modulating hormone levels, and improving immune function.

  7. Enhance mental well-being: Exercise releases endorphins, which are natural mood-boosting chemicals that help reduce stress, anxiety, and depression, improving overall mental well-being and quality of life in individuals with breast cancer.
