Tilly tots,

Hi and welcome to Grace. I'm very sorry to know of your multiple occurrences of cancer. Your statement that your quitting smoking was too late is incorrect. No matter when you stop it's a good thing moving forward. My husband is a good example. He stopped when he was diagnosed, we both did. He was successful in part due to a 9 day stay in the hospital during which time he was formally diagnosed. It has been a great help to his health. His very difficult to treat squamous nsclc was cured with radiation and chemo. Smoking allowed him to tolerate treatment better and to breath easier even if still easily short of breath. So a BIG Congratulations on stopping!

I'm posting the following link with the understanding that I'll check with one of our faculty to make sure the info is correct. I understand there to be a multitude of variants of this mutation but can't find that there is the same on that is related to lung cancer is also related to breast cancer.

I or one of our faculty will post again within a day.
All best,
Janine

Hi Tilly tots,

I contacted Dr. West, he stated he isn't aware of any work on answering the question of whether the BRCA2 mutation variant that causes lung cancer is related to the BRCA mutation variant that causes breast cancer.

In my internet search I've not been able to find any evidence of work on it either. It's all too possible the article I referred you to hasn't taken into consideration that there are different variants of these mutations that can cause cancers. It's likely that article isn't being as specific as we are; can the same mutation you have have caused both/all your cancers. I'm afraid we can't give you an answer though it is a very relevant question.

I hope you do well and hope you don't get anymore cancers.
All best,
Janine
