Introduction
Undergoing a mastectomy (surgical removal of one or both breasts) is a significant step in breast cancer treatment. While the procedure is often successful, infections can sometimes occur during recovery. If you or a loved one is dealing with a post-mastectomy infection, it’s important to recognise the signs early and seek proper treatment. This article will help you understand what a post-mastectomy infection is, common symptoms to watch for, causes and risk factors, treatment options and prevention and self-care tips.
What Is a Post-Mastectomy Infection?
A post-mastectomy infection occurs when bacteria enter the surgical wound, leading to inflammation, pain, and sometimes fever. While infections are not extremely common, they can delay healing and require medical attention.
Symptoms of Post-Mastectomy Infection
If you notice any of these signs after surgery, contact your doctor promptly:
Increased pain, redness, or warmth around the incision
Swelling or pus (yellow or green discharge) from the wound
Fever (temperature above 100.4°F or 38°C)
Foul-smelling odor from the incision
Increased fatigue or feeling unwell
Early detection and treatment can prevent complications, so don’t ignore these symptoms.
Causes and Risk Factors
Several factors can increase the risk of infection after mastectomy:
Weakened immune system (due to chemotherapy or other conditions)
Diabetes or obesity, which slow healing
Smoking, as it reduces blood flow to tissues
Poor wound care (not keeping the area clean and dry)
Drainage tubes (if not properly maintained, they can introduce bacteria)

How Are Post-Mastectomy Infections Treated?
Treatment depends on the severity of the infection but may include:
1. Antibiotics
Oral or IV antibiotics are usually the first line of treatment.
Finish the full course, even if symptoms improve.
2. Wound Care
Your doctor may clean and dress the wound.
If there’s an abscess (pocket of pus), it might need drainage.
3. Pain Management
Over-the-counter pain relievers (like acetaminophen) can help.
Avoid aspirin if you’re on blood thinners.
4. Hospitalisation (In Severe Cases)
If the infection spreads, IV antibiotics and monitoring may be needed.
How Can You Prevent Infections?
Ways to prevent infection after mastectomy are:
1. Follow Wound Care Instructions
Keep the incision clean and dry.
Change dressings as directed.
Avoid soaking in baths or pools until fully healed.
2. Watch for Warning Signs
Check the incision daily for redness, swelling, or discharge.
3. Maintain Good Hygiene
Wash hands before touching the wound.
Wear loose, breathable clothing to prevent irritation.
4. Boost Your Immune System
Eat a balanced diet rich in protein, vitamins, and minerals.
Stay hydrated and get enough rest.
5. Avoid Smoking and Alcohol
Both can slow healing and increase infection risk.
When to See a Doctor?
Seek immediate medical help if you experience:
High fever (over 101°F or 38.3°C)
Severe pain or swelling
Pus or foul-smelling discharge
Increased redness spreading beyond the incision
Recovery and Emotional Support
Healing after mastectomy is not just physical, it’s emotional too. Infections can be frustrating, but with proper care, most recover fully. Consider:
Joining a support group for breast cancer survivors.
Talking to a counsellor if you feel anxious or overwhelmed.
Gentle exercises (as approved by your doctor) to improve circulation.
Conclusion
Post-mastectomy infections, while concerning, are treatable. By recognising symptoms early, following medical advice, and taking preventive steps, you can support your healing journey. Stay vigilant, prioritise self-care, and lean on your healthcare team for support.
