Have you experienced side effects or concerns after lumpectomy and radiation for DCIS without being able to take aromatase inhibitors?

Many people with DCIS have gone through lumpectomy followed by radiation therapy. This is a very common treatment approach. After a lumpectomy, most people receive radiation therapy to destroy any remaining cancer cells and reduce the risk of recurrence.

The good news is that DCIS has an excellent outlook. About 98 percent of people with DCIS survive 10 years or more after diagnosis. Once the affected breast tissue is removed through surgery, people with DCIS have a five-year survival rate greater than 99 percent.

Regarding not being able to take aromatase inhibitors - while hormone therapy like tamoxifen is often recommended after surgery for hormone receptor-positive DCIS to reduce recurrence risk, it's not always necessary for everyone. The treatment you've already received (lumpectomy and radiation) is often very effective at eliminating breast cancer.

People who have a lumpectomy followed by radiation therapy have up to a 15 percent chance of relapse, compared to 25-30 percent for lumpectomy alone. This shows that radiation adds significant protection even without hormone therapy.

You'll continue having follow-up visits with your doctor to monitor healing and watch for any signs of cancer. Many people have physical exams and screening tests once or twice per year after treatment.
