Breast Cancer: Everything You Need to Know, from Diagnosis to Prevention
Breast cancer is a significant public health concern, affecting individuals worldwide. In India, the incidence of breast cancer has been steadily increasing in recent years. According to the Indian Council of Medical Research (ICMR), breast cancer is now the most common cancer among Indian women. In fact, recent estimates [1] suggest that approximately 1.5 lakh new cases are diagnosed each year. This data is a stark reminder of the urgency to address this issue and raise awareness about early detection and prevention.
Here’s everything you need to know about the condition, along with effective prevention tips and the importance of screening.
Symptoms, Diagnosis, and Treatment Options
Early detection is crucial for effective breast cancer treatment. Being aware of the common symptoms and seeking medical attention promptly can make a significant difference in treatment outcomes. Remember, breast cancer is successfully treatable when detected and treated early. The symptoms of breast cancer include:
- Lump(s) or thickening in the breast or underarm
- Change in the size, shape, or appearance of the breast
- Unexplained pain in the breast or nipple
- Nipple discharge other than breast milk
- Skin changes on the breast, such as redness, dimpling, or scaling
If you notice any of these symptoms, you should visit your family physician to discuss the cause of these symptoms further.
The diagnosis of breast cancer typically involves a combination of methods, including a clinical breast exam, mammography, ultrasound, and biopsy.
Once diagnosed, your treatment options can vary depending on the stage and type of cancer. They may include surgery, chemotherapy, radiation therapy, targeted therapy, Immunotherapy and hormonal therapy. Further, your treatment plan will, most likely, be tailored to your specific diagnosis, and it is crucial to discuss all available options with your medical team to make informed decisions.
Screening, and why it is Important
Breast cancer, like many other cancers, can be a silent killer. You might not notice symptoms of the disease for several months or years before it is detected. This is why regular screening is imperative to detect cancer early. When detected early, breast cancer is more likely to have successful treatment outcomes and very high cure rates.
The goal of screening is to detect cancer before it causes symptoms, making it easier to treat and potentially preventing it from spreading.
As per the American Cancer Society, a woman should start screening for breast cancer with mammograms, every year starting at age 40[2]. Women at high risk for breast cancer, such as those individuals with strong family history of breast cancer may need to start screening earlier. While, this is a general recommendation, it is important to talk to your doctor about when you should start screening for breast cancer based on your individual risk factors.
The best way to screen for breast cancer is by performing regular breast self-exams and getting a mammogram once every year. But if you notice any of the symptoms mentioned above, you should visit your doctor immediately to get them investigated.
Importance of Breast Self-Exams
Breast self-exams are a simple yet powerful tool to detect breast cancer early. Conducting regular breast self-exams can help you become familiar with your body, helping you notice any changes as soon as they occur. Here’s a step-by-step guide on how to perform a breast self-exam:
- Stand in front of a mirror and inspect your breasts for any visible changes, such as dimpling, puckering, or changes in the nipple’s position.
- Raise your arms above your head and look for the same changes.
- Lie down and use your opposite hand to feel your breast using a circular motion, checking for lumps or abnormalities.
- Repeat the process for the other breast.
Performing breast self-exams should become a monthly routine, preferably a few days after your menstrual cycle. If you notice any changes or have concerns, consult a healthcare professional for further evaluation.
Risk factors:
Certain factors can increase your risk of developing breast cancer. Being aware of these risk factors can help you make informed lifestyle choices and consider regular screenings earlier than recommended. Some common risk factors include:
- Age: The risk of breast cancer increases with age, particularly after 40.
- Family history: A family history of breast cancer can raise your risk, especially if close relatives have had the disease.
- Genetic mutations: Inherited genetic mutations, such as BRCA1 and BRCA2, can significantly increase your risk of developing breast cancer. Getting tested for this gene mutation is paramount, especially if you have a family history of the disease.
- Hormone replacement therapy: Long-term use of hormone replacement therapy may increase your risk of breast cancer as well. It is best to speak to your treating physician about this if you have any concerns.
- Reproductive factors: Early menstruation, late menopause, and having children at an older age can all raise your risk of developing breast cancer.
- Excessive alcohol consumption: Regular, heavy alcohol consumption may also increase your risk of breast cancer.
- Obesity: Being overweight or obese can also raise your risk of developing breast cancer. Having a high amount of body fat or adipose tissue can lead to the release of high levels of estrogen, which has been linked to an increased risk of breast, endometrial, ovarian, and some other cancers.
Understanding these risk factors is essential for making lifestyle choices and seeking appropriate screenings, especially if several risk factors apply to you.
Tips for prevention:
Preventing breast cancer is not always possible, but there are steps you can take to reduce your risk and promote breast health:
- Maintain a healthy lifestyle: Eating a healthy and nutritious diet, exercising regularly and maintaining a healthy weight can all help prevent or delay the onset of breast cancer.
- Limit alcohol consumption: If you do drink alcohol, do so in moderation.
- Breastfeeding: If possible, breastfeed your children, as it can reduce the risk of breast cancer.
- Get regular screenings: This is especially true if you have any of the above-mentioned risk factors. Even otherwise, you should start screening for the disease once you reach the age of 40.
- Know and understand your family history: Be aware of your family’s cancer history and discuss it with your healthcare provider.
- Undergo genetic testing: If you have a strong family history of breast cancer, consider genetic counselling and testing for the BRACA1 and BRACA2 genes.
- Speak up about hormone therapy: Discuss the risks and benefits of hormone replacement therapy with your physician, if you are on this form of treatment.
- Do regular breast self-exams: Conduct regular breast self-exams and promptly report any changes or concerns.
The Importance of Early Detection
Breast cancer is a formidable adversary, but with early detection and timely intervention, it can be treated successfully. Regular screenings, being awareness of the symptoms, and self-exams are powerful tools in the battle against breast cancer. Equally important is having a support network of family and loved ones who understand the significance of early detection and encourage regular check-ups.
In conclusion, remember that early detection saves lives. Spread awareness about the importance of breast health, be proactive in monitoring your own well-being, and encourage your loved ones to do the same. By working together and staying informed, we can make significant strides in the fight against breast cancer and improve the chances of a brighter, healthier future.

Haemophilia
#Haemophilia: Women and Girls Bleed Too #LightUpRed Haemophilia is often thought of as a “man’s disease,” but women and girls can have it too. Though less commonly diagnosed, females with haemophilia can experience significant bleeding issues that impact their daily lives. Understanding Haemophilia in Women Haemophilia is a genetic disorder where the blood doesn’t clot properly due to a deficiency in clotting factors. It’s linked to the X chromosome, meaning males (who have one X) are more likely to have severe symptoms. However, females (who have two X chromosomes) can also inherit the mutation. Traditionally, women were labelled as “carriers,” but many actually have mild, moderate, or even severe haemophilia. Symptoms in Women and Girls Women with haemophilia or low clotting factor levels may experience: Heavy and prolonged menstrual periods (menorrhagia) Frequent nosebleeds and easy bruising Excessive bleeding after childbirth, surgery, or dental work Joint and muscle bleeds, similar to male patients These symptoms are often overlooked or misdiagnosed, leading to delayed treatment. Challenges in Diagnosis and Care Many doctors still hesitate to diagnose women with haemophilia, instead labelling them as carriers. This medical bias means women often struggle for years before getting proper care. Additionally, female-specific issues—like menstrual bleeding—are sometimes dismissed as normal, even when they indicate an underlying bleeding disorder. Treatment and Management Women with haemophilia can benefit from the same treatments as men, including: Clotting factor replacement therapy Antifibrinolytic drugs (to reduce bleeding) Hormonal treatments to manage menstrual bleeding Preventive care to protect joints from damage Raising awareness is crucial for ensuring timely diagnosis and treatment for women and girls with haemophilia. No one should suffer due to outdated misconceptions. Breaking the Stigma The idea that “only men bleed” has been debunked—women and girls with haemophilia deserve recognition, care, and support. Advocacy groups, medical professionals, and patients are working together to push for better diagnosis, treatment, and awareness. It’s time to change the narrative: Women bleed too, and they deserve the care they need. Book an Appointment

Hereditary Colorectal Cancer Awareness
Hereditary Colorectal Cancer Awareness Colorectal cancer (CRC) can be inherited in 10-15% of cases. Hereditary colorectal cancer awareness in India is still low despite rising cases. Many cases go undiagnosed due to lack of genetic testing, limited awareness and social stigma around discussing cancer. Types of Hereditary CRC Lynch Syndrome (HNPCC): – Accounts for ~3% of CRC cases, caused by mutations in DNA mismatch repair genes such as MLH1, MHS2, MSH6 and PMS2. Familial Adenomatous Polyposis (FAP): – Resulting from the mutation of APC gene, causing hundreds to thousands of polyps in the colon, leading to near-certain CRC if untreated. MUTYH – associated Polyposis (MAP): – Caused by mutations in MUTYH gene. Peutz – Jeughers Syndrome: Associated with mutation in STK11 gene. Cowden Syndrome: Caused by mutations in PTEN gene. Juvenile Polyposis Syndrome: Associated with mutation in BMPR1A and SMAD4 gene. Additionally, recent advancements in molecular techniques have identified new genes involved in CRC predisposition, including RPS20, POLE, POLD1, AXIN2, NTLH1, RNF43 AND GREM1. Who is at Risk? Individuals with a family history of CRC, especially if diagnosed before age 50. Those with a personal or family history of polyps. People with Lynch syndrome or FAP mutations. Certain Early Detection & Prevention Screening: – Colonoscopies starting at age 40 (or earlier if family history is strong). Genetic Testing: – Recommended for families with multiple CRC cases. Lifestyle Changes: – A healthy diet, regular exercise, and avoiding smoking/alcohol can lower risk. Awareness & Action Educate families about genetic risks. Encourage genetic counseling for high-risk individuals. Promote early screening to prevent CRC development. Book an Appointment
