Best diet to prevent breast cancer naturally

Breast cancer is a type of cancer that originates in the cells of the breast tissue. It can occur in both women and men, but it is far more common in women. The cancer usually begins in the milk-producing ducts or the glandular tissue of the breast. Over time, the cancer cells can grow and spread to other parts of the body, such as the lymph nodes, bones, liver, lungs, or brain.

India ranks highest in number of estimated breast cancer deaths (98,337) for the year 2022 among females.

SYMPTOMS OF BREAST CANCER

Common signs and symptoms of breast cancer include:

• A lump in the breast or underarm area.
• Change in the size, shape, or appearance of the breast.
• Pain in the breast or nipple area.
• Unexplained nipple discharge, other than breast milk.
• Skin changes like redness, dimpling, or thickening of the breast skin.
• Swelling or enlargement of a breast, even without a lump.

Breast cancer is the commonest malignancy among women globally. It has now surpassed lung cancer as the leading cause of global cancer incidence in 2020, with an estimated 2.3 million new cases. Epidemiological studies have shown that the global burden is expected to cross almost 2 million by the year 2030.

When it comes to the 5-year overall survival, a study reported it to be 95% for stage I patients, 92% for stage II, 70% for stage III and only 21% for stage IV patients. The survival rate of patients with breast cancer is poor in India as compared to Western countries due to earlier age at onset, late stage of disease at presentation.

In India, nearly 60% of BC cases are diagnosed at stage III or IV of the disease. Most of the patients present to the healthcare facility only when there is a large palpable mass or secondary changes like local skin/chest wall changes are visible. Women tend to ignore the minor symptoms and do not show up at the hospital until it is unbearable, owing to their household responsibilities. Other factors that may contribute to the late presentation include a lack of awareness about the disease, especially in rural areas.

In developed countries, modified lifestyle, delayed age for marriage, late first child, late-night work schedule, and hormonal replacement therapy are the major risk factors for breast cancer development. In developing countries, the main reasons for high breast cancer incidence and mortality are lack of proper awareness or knowledge of the disease, inappropriate screening programs, delayed diagnosis, and insufficient medical facilities. There are multiple therapies available for breast cancer treatment including surgery, radiotherapy, chemotherapy, endotherapy, and immunotherapy.

Risk factors including late age for marriage, first childbirth, and menopause are strongly associated with disease development. A study estimated the risk of 7.0% (95% confidence interval: 5.2, 9.1) in women who married at age 30 or older, relative to women who married at a younger age (~20 year), whereas the corresponding risk was 1.4% (95% confidence interval: 1.1, 1.8) when marriage age was less than 30 but the first childbirth age is 30 or more. Late age at marriage and childbirth leads to lack of breast tissue differentiation, more exposure to nonestrogenic mutagens, and genotoxicity by estrogen. Menopause after 50 years of age puts the women at prolonged estrogen exposure. A meta-analysis study observed that early pregnancy and longer breastfeeding duration reduce ER (Estrogen receptor) positive and ER negative breast cancer risk. Similarly, unbalanced diet intake is another factor associated with breast cancer risk.

Study estimated that women on nonvegetarian and high animal fat diet had more chance of breast cancer development than women on vegetarian diet. Further, poor physical activity also correlated to breast cancer risk. In a case-control study conducted in the south Indian population determined that women engaged in household activities had low breast cancer risk compared to women not involved in household activities.

In addition, obesity (high waist-to-hip ratio) is another strong risk factor for breast cancer in postmenopausal women and also associated with poor disease outcome in women of all ages. In the United States, about 18% of premenopausal women have elevated BMI and are at high breast cancer development risk. It was observed that postmenopausal women with ≥5.0 BMI (Body Mass Index) and ≥90 cm abdominal circumference were more likely to develop breast cancer. It results from the activity and accumulation of polycyclic aromatic hydrocarbons (PAH) in breast fat tissue. In the breast fat tissue, PAH interacts with the cellular estrogen receptor to enhance the risk of development of breast cancer. Besides, another study noted that obese women with breast cancer have worse disease-free and overall survival than nonobese women with breast cancer.

There are multiple demographic, social and biomedical risk factors of breast cancer. Age of the women, early age at menarche, delayed first birth and menopause, nulliparity, short duration lactation, use of birth control pills, obesity, excess consumption of fats, hormone replacements and more importantly women having family history are considered as significant risk factors of breast cancer by various epidemiological and clinical studies.

Further, this study found breast cancer risk was 8 times higher among unmarried women, 3 times more among nulliparous women, 2 times more likely among post-menopausal women, 10 times more among those who had never breastfed, 1.5 times higher among women who were exposed to hormonal contraceptives and 4.5 time more likely among women with history of ovarian diseases than in comparison to married, non-nulliparous, premenopausal, women who ever breastfed, who have not been exposed to hormonal contraceptives, and women without any ovarian diseases respectively.

A family history of breast cancer significantly increases the risk. Genetic mutations such as BRCA1 and BRCA2 also contribute to the development of breast cancer.

 

Early puberty	At puberty, undifferentiated, proliferative breast cells increase rapidly and more exposure to hormonal changes increases susceptibility to mutagens
Early menarche	At menarche, breast cells tend to grow and divide increasing the risk of breast cancer
Late marriage age	Prolong exposure to estrogen hormone
Late child birth age	Lack of breast tissue differentiation and prolong exposure to estrogen hormone
Lactation failure	Lack of breast tissue differentiation, more susceptible to nonestrogenic mutagens and estrogen
Late menopause age	Late onset of breast involution and prolong exposure to estrogen and progesterone
Lack of physical activity	Reduced exposure to sex hormones due to increase the number of anovulatory cycles
High fat diet	Cholesterol activate estrogen signalling and cell proliferation
Obesity	Increased levels of inflammatory cytokines and chemokines
Alcohol consumption	Increase estrogen hormone
Smoking	Induce gene mutations such as p53 gene mutation and DNA adducts
HRT	Prolong exposure to estrogen hormone
Contraceptive	Contraceptives contain progesterone and estrogen
Family history	BRCA1/2 gene mutations
Environmental toxicants	Pollutants can disrupt endocrine signalling

 

Treatment

The treatment for breast cancer depends on several factors, including the type and stage of cancer, and the patient’s overall health. Common treatment options include:

• Surgery: Removing the tumor or the entire breast (mastectomy) is one of the primary treatment options.
• Chemotherapy: Drugs that kill or inhibit the growth of cancer cells, often used after surgery to reduce the risk of recurrence or when cancer has spread.
• Radiation Therapy: High-energy rays are used to target cancer cells, typically after surgery to eliminate any remaining cancer cells.
• Hormone Therapy: Used for cancers that are hormone receptor-positive, blocking the hormones that fuel cancer growth (e.g., estrogen or progesterone).
• Targeted Therapy: Drugs that target specific molecules involved in cancer cell growth (e.g., HER2-targeted therapies).
• Immunotherapy: Uses the body’s immune system to fight cancer.
• Supportive Care: Helps manage symptoms and improve quality of life during treatment.

Prevention

While there’s no guaranteed way to prevent breast cancer, several steps can help lower the risk:

• Regular Screening: Early detection through mammograms can lead to more effective treatment. Women over 40 are typically advised to get annual mammograms, but this may vary based on personal and family history.
• Maintain a Healthy Lifestyle: Regular exercise, a healthy diet, limiting alcohol intake, and avoiding smoking can help reduce the risk of breast cancer.
• Breastfeeding: If possible, breastfeeding can reduce the risk, especially when done for extended periods.
• Hormonal Control: Limiting the use of hormone replacement therapy (HRT) after menopause can lower the risk.

Conclusion

Breast cancer is one of the most common cancers affecting women, and early detection can make all the difference. Awareness, regular screening, and recognizing symptoms on time greatly increase survival rates. A healthy lifestyle, balanced diet, physical activity, breastfeeding, and avoiding smoking and alcohol can help reduce the risk.
