Hey everyone 👋 So back in 2023 when I was 28 I was diagnosed with acute myeloid leukaemia. I had chemo then onto a...

Understanding Your Increased Cancer Risk After AML Treatment

Thank you for sharing this important health concern. I want to address what your consultant mentioned and help you understand why you're at higher risk.

Why AML Treatment Increases Breast Cancer Risk

The chemotherapy you received for acute myeloid leukemia (AML) and your stem cell transplant can increase your risk of developing secondary cancers—meaning new cancers that develop as a side effect of cancer treatment itself. This is a real and documented concern that oncologists monitor carefully.

Key points about your situation:

• Chemotherapy exposure: Certain chemotherapy drugs used in AML treatment (particularly alkylating agents) are known to increase breast cancer risk years later
• Stem cell transplant: The conditioning regimen (intensive chemotherapy/radiation) before transplant also increases this risk
• Age factor: Being diagnosed at 28 means you have many decades ahead where cancer could potentially develop
• Gender: If you were assigned female at birth, breast tissue is particularly sensitive to chemotherapy-related damage

According to NCCN Guidelines, patients with a history of chest radiation or certain chemotherapy regimens should be monitored for secondary malignancies, including breast cancer.

About Your Sore Underarms

The soreness in your underarms (axillae) is worth investigating with your medical team. This could be:

• Lymph node swelling (lymphadenopathy) - your underarms contain many lymph nodes that can become enlarged from infection, inflammation, or other causes
• Muscle soreness from treatment side effects or physical changes
• Nerve-related pain (neuropathy) from chemotherapy
• Something unrelated to your cancer history

This needs evaluation by your healthcare team—don't wait on this.

What You Should Do Now

1. Schedule an Urgent Appointment

Contact your oncologist or primary care doctor about the underarm soreness. Mention:

• When it started
• Whether it's one side or both
• If you notice any lumps, swelling, or skin changes
• Any other symptoms (fever, night sweats, fatigue)

2. Discuss Breast Cancer Screening

Even though you're young and don't qualify for routine mammograms yet, your history changes this. Ask your doctor about:

• When to start screening: Your oncologist may recommend earlier screening than standard guidelines
• What type of screening: This might include:
  • Clinical breast exams (physical exams by a healthcare provider)
  • Mammograms (low-dose x-ray images of breast tissue)
  • Possibly breast MRI (magnetic resonance imaging), which uses radio waves and magnets to create detailed images

According to NCCN Guidelines for Breast Cancer Screening, patients with significant risk factors may need screening earlier and more frequently than average-risk women.

3. Skin Cancer Monitoring

Your consultant also mentioned skin cancer risk. This is because:

• Chemotherapy can increase melanoma and other skin cancer risk
• You should do monthly self-skin checks
• See a dermatologist (skin specialist) annually or if you notice any changing moles

Questions to Ask Your Oncology Team

1. "Given my AML treatment history, when should I start breast cancer screening?"
2. "What type of screening do you recommend—mammogram, MRI, or clinical exams?"
3. "How often should I be screened?"
4. "What should I watch for between appointments?"
5. "Can you evaluate this underarm soreness and determine if imaging is needed?"
6. "Should I see a dermatologist for skin cancer screening?"
7. "Are there any other secondary cancer risks I should know about?"
8. "What lifestyle factors can I control to reduce my cancer risk?" (exercise, avoiding smoking, limiting alcohol, sun protection)

Important Context

Being a cancer survivor doesn't mean you'll definitely develop another cancer. Many people treated for AML live long, healthy lives without secondary cancers. However, your medical team is right to monitor you proactively. Early detection of any cancer is always better than late detection.

The underarm soreness needs prompt evaluation—this isn't something to monitor at home. Contact your doctor this week if possible.
