Introduction
Mastitis and breast cancer are different diseases that affect the breast. However, new research is exploring a possible link between them. Mastitis is an inflammatory condition that predominantly happens in females who are nursing breast milk.
Breast cancer, on the other hand, is a serious and possibly fatal disease that causes breast tissue to grow abnormally. Clinical research is now looking into the idea that mastitis might be an early sign of a higher chance of getting breast cancer. To get an early diagnosis and better health results for women, it’s important to understand this relationship. Around the age of 40 to 49, females have a higher chance of having breast cancer.
What is Mastitis?
Mastitis is a swelling of the breast tissue that frequently results in infection. It usually happens in the early stages of breastfeeding, but it can sometimes afflict non-lactating women as well. The syndrome happens when milk gets stuck in a milk duct. This blockage creates a good setting for bacteria to grow, especially Staphylococcus aureus.
Mastitis has the following primary symptoms:
Localized breast discomfort, tenderness, and edema
Redness and warmth of skin
A lump or thickened region in the breast.
Fever, chills, flu-like symptoms.

It is recorded that this affects around 10 percent of the female population in America. It has the potential to reach up to 30 percent of females breastfeeding worldwide. It is quite usual in the trimester of breastfeeding.
What is Breast Cancer?
Breast cancer is a stubborn tumor that grows from chest cells, often starting in the ducts or lobules. Breast cancer is a very common cancer in females globally. Each year, there are over 2.3 million new cases and more than 685,000 deaths, according to the World Health Organization.
There are various kinds of breast cancer, such as:
Common symptoms include:
Mastitis vs. Breast Cancer: Understanding the Confusion
Mastitis and breast cancer, especially inflammatory breast cancer (IBC), can have symptoms that are similar to each other. This can cause a wrong diagnosis or a delay in treatment. Redness, swelling, pain, and changes in the texture of the skin may be signs of both diseases. But there are important differences:
Mastitis usually comes on quickly while nursing and goes away with antibiotics. It is common for fever and other systemic signs to happen at the exact time.
If you have IBC, a rare but aggressive type of breast cancer, your skin may also get thicker, swell up, and turn red. However, it doesn’t respond to medicines and doesn’t give you flu-like symptoms like mastitis does.

This diagram shows how inflammatory breast cancer and mastitis have similar symptoms. These include breast soreness, swelling, and redness. Inflammatory breast cancer causes nipple retraction and lymph node swelling, while mastitis causes fever, flu-like symptoms, and alterations. Early diagnosis requires recognizing these discrepancies.
Does Mastitis Increase Breast Cancer Risk?
Many studies show that recurrent or chronic mastitis may raise the risk of breast cancer later in life.
A 2019 study in Scientific Reports looked at information from over 8,600 women who had a history of mastitis. The study found that these women had a 3.71-fold higher chance of being diagnosed with breast cancer than women who had not had a history of mastitis. The suggested mechanisms are the following:

Inflammation that lasts for a long time can damage DNA and stress cells.
Immune system imbalance, which makes it harder for the body to find and get rid of abnormal cells
Changes in the structure of breast tissue that are caused by repeated infections
A lump that returns or stays the same after mastitis should not be ignored. It might be a cancerous growth that was overlooked during the infection. This calls for a full medical workup, which may include a biopsy, mammography, ultrasound, or MRI.
Implications for Women’s Health
Increased Vigilance:
Women with a history of mastitis, especially recurring or non-lactational, should be more careful about any lasting changes in their breasts.
Enhanced Screening:
Routine breast screening (ultrasound, mammography) may be advised for individuals with recurrent mastitis episodes.
Risk Awareness:
Understanding the link between chronic mastitis and a higher risk of breast cancer helps women make better health choices.
Clinical Follow-Up:
Regular check-ups with doctors can help find cancer early in people at high risk.
Utilization of preventative Therapies:
In some cases, doctors may consider preventative drugs like Exesin 25 mg, Ramiven 100 mg, or Evermil 10 mg. This must be done under the lookout of a cancer doctor.

This graph shows that over 10 years, women with a history of mastitis (red line) have a higher chance of developing breast cancer (2.9%). In contrast, women without mastitis (green line) have a lower chance (2.4%). The difference is statistically significant (p = 0.004), which means that mastitis may be linked to a slightly higher risk of getting breast cancer in the long run.
How Is Mastitis Diagnosed and Treated?
Diagnosed:
Clinical examination to check for edema, soreness, and erythema
Patient history, particularly connected to nursing.
If there’s a persistent lump or suspicion of an abscess or cancer, get an ultrasound.
Breast biopsy in non-responsive or unusual situations to rule out malignancy.
Treatment:
Common antibiotic regimens include dicloxacillin and cephalexin.
MRSA coverage may be required.
Warm compresses and massage help promote milk flow and minimize inflammation.
Ibuprofen and other NSAIDs are utilized to lessen aches and high temperatures.
To ease milk stasis, either continue breastfeeding or express milk.
Needle aspiration or surgical drainage in the event of an abscess
Complete the entire antibiotic course to avoid recurrence or problems.
Does having mastitis increase your lifetime breast cancer risk?
Reports show that recurrent or chronic mastitis may minimally increase the chance of breast cancer.
Long-term tissue changes linked to cancer may result from breast inflammation.
According to longitudinal research, women with mastitis had a greater breast cancer risk.
Monitoring is crucial due to the tiny but statistically significant risk increase.
Mastitis-prone women should be screened and treated promptly.
Conclusion
Mastitis is a treatable disease that is often linked to breastfeeding. However, if it happens more than once or when the woman isn’t breastfeeding, it may mean she is more likely to get breast cancer. Mastitis is not a cause, but it can be a biological sign that tells patients and doctors that they need to look into it more.
Women must take care of their breast health. If they notice mastitis, they must treat it quickly. Also, if symptoms persist, they should seek a proper diagnosis. You can reduce long-term risks by combining preventive measures. This includes lifestyle changes and, sometimes, hormonal treatments like Ramiven, Exesin, or Evermil. Early detection and quick treatment are still the most important parts of managing breast health well.
