Agree with Laura, my options were just as she stated, Mastectomy and no radiation, or the lumpectomy with the radiation. Keeping you in prayers as you review all the info to make the decisions that are right for you! Hugs!

Generally it is a mastectomy or lumpectomy with radiation to try to prevent recurrence

Great questions! With stage 0 DCIS, radiation isn't always required — but it's commonly recommended after a lumpectomy (breast-conserving surgery) to lower the chances of the cancer coming back.

Great questions! With stage 0 DCIS, radiation isn't always required — but it's commonly recommended after a lumpectomy (breast-conserving surgery) to lower the chances of the cancer coming back.

Here's why radiation is often suggested after a lumpectomy:

- A lumpectomy removes the tumor but leaves some breast tissue behind
- Radiation targets any remaining cancer cells that might not be visible
- Together, lumpectomy + radiation is the most common treatment path for DCIS

If a mastectomy is chosen instead (removing the whole breast), radiation is typically not needed. As for being ER and PR positive, that's actually useful information! It means the cancer cells are fueled by the hormones estrogen and progesterone.

Because of this, hormone therapy (like tamoxifen) is often recommended after surgery. The goal is to:

- Reduce the risk of the cancer returning
- Help prevent it from progressing to a more invasive form

So being hormone receptor-positive opens the door to hormone therapy as an additional layer of protection. It's worth having a detailed conversation with your oncologist about which combination of treatments makes the most sense for your specific situation.

Hi.. I was also stage 0 DCIS estrogen positive and just completed 21 rounds of radiation.
