@skiwi Welcome to our community and hopefully we can be of help to you and your mother as she moves through this journey of cancer treatment.
Yes, it is important to have an oncologist trained in gynecological cancers once diagnosed. You want the expertise they bring to treatment. That said, don't rely too much on the website to understand your gynecologist's skills. I've found those profiles often quite inaccurate and often out of date. That said, I'm not surprised she's listed with the other disciplines. Much OVC treatment is similar to and often pulled from treatment for lung and gastrointestinal cancers. I believe there are several of the newer drugs we now use for OVC that were actually developed for lung cancer originally. Additionally, some of the provincial models for cancer care have the oncology departments working in teams where each play off the other's expertise. That could also be the case here.
There is nothing wrong about just asking her oncologist about her background and training. You can do that diplomatically and without offending. You've already stated you both like her so just start with that and then explain your underlying need to ensure your mother is in the hands of the expertise needed to treat her and ask the questions. I'm sure she'll put your mind at ease and if not, then asking for a referral to someone with more of a specialty in gynecological issues is an option. If you're still not comfortable to have that discussion yourself then perhaps your family physician could intervene.
Regardless, do know that you're in good hands in the BC system. It is world renowned for cancer research and treatment. And I hope your mother's chemo goes well. I am assuming from the timing mentioned that the current chemo is part of an overall primary treatment plan. Many of them are very successful at conclusion these days so I wish that for your mother.
Do keep in touch and let us know where we can be of help down the road. You and she will be in our thoughts.
