That's such a frustrating and understandably confusing situation. There are a few reasons why a biopsy might miss endometrial cancer, even when it's present.

A biopsy only samples a small amount of tissue, so cancer cells in other areas of the uterus or beyond may not be captured in that sample. Stage 3 endometrial cancer means the cancer has spread outside the uterus into the pelvic area — such as the ovaries, fallopian tubes, vagina, or nearby lymph nodes. A standard endometrial biopsy focuses on the uterine lining, so spread to these surrounding areas wouldn't necessarily show up in that sample.

Here are some other reasons a biopsy might miss it:

- The cancer may have been at an earlier stage at the time of the biopsy and progressed quickly
- Scar tissue can sometimes make it harder to collect a complete tissue sample
- Staging isn't always final until after surgery, when the full tumor and lymph nodes are examined more thoroughly

It's worth having an open conversation with your oncologist about the timeline and what the diagnostic process revealed. You deserve clear answers.
