A YouTube video (by Jenn Simmons, MD) arguing that 80% of DCIS (Ductal Carcinoma In Situ) will never progress to invasive cancer and that most people with DCIS are therefore overtreated. The speaker describes the standard care pathway (surgery — mastectomy or partial mastectomy — followed by about six to seven weeks of radiation and years of medication) and recounts her own initial trust and surprise when given the diagnosis and options.

Questions this video answers

80%

Mastectomy or a partial mastectomy.

Chapters

Newer research shows that 80% of DCIS will never become cancer. So that means 80% are being over treated because all people diagnosed with DCIS get the same standard of care. Treatment, cut, burn, poison. It's surgery, weeks of radiation, and then years of drugs. This is what was told to me, and I was a very trusting person. You know, I didn't have any reason to research or question the medical community until I was told you have pre cancer called dcis. And the treatment options are a mastectomy or a partial mastectomy, six, seven weeks of radiation.
