Patient discussion about metaplasia.

Q. what is fragments of endocervical glandular mucosa with inflammation and squamous metaplasia fragments of endocervical glandular mucosa

A. It means that part of the mucose on the cervix area has changes from a certain kind of mucose cells to another, and that there is a bit of an inflammation around it. This should be brought to the knowledge of a gynecologist and be monitored by him/her.

Q. what is metaplasia i had 2 surgeries in my left breast for some cyst they found metaplasia in the biopsy

A. from what i remember while reading on the subject- cells can go through different changes. one of them is metaplasia- change of form. our body is amazingly flexible, and under stress cells can change form and function. like if you have continues heartburns, cells in your esophagus will change to cells similar to the stomach and start excreting anti acid materials. finding that on a biopsy means the cells in the cyst changed function.
