As I donít want to have any kind of problems with SEO issues in the future, I was asking that will it be bad for the site if I blog about cancer on my site.
To clarify, you have:
You're looking to write some content regarding cancer and paste it on the "domain-about-cosmetics.com" location - is that right?
If you're going to hit the niche hard, then you might want to get "cancer.domain-about-cosmetics.com" or other domain specifically for the cancer topcs and then cross reference them.
Putting content on your existing blog about cancer should not negatively affect your current ratings for your existing keywords on your site. Adding more content targeting a different keyword/niche (cancer), would just mean more exposure of your domain to a different audience.
