I've had breast pain for 2 months and tissue seems denser than other breast. if it were inflammatory breast cancer would symptoms be worse by now?

Usually no pain: Inflammatory breast cancer (IBC) usually is diffuse swelling, enlargement, heaviness, redness, and skin swelling. Pain is rare in breast cancer, unless it is so advanced that it has eroded out through the skin, or eating into the underlying muscles. By that time, there is an obvious large hard mass. Lobular breast cancer can show up like this, however, and I strongly urge you to see a dr soon!

IBC: IBC is a very aggressive form of cancer causing redness and swelling, thus the name inflammatory. What you describe does not sound like inflammatory breast cancer (especially if to has not turned into a dreadful mess after those 2 months) but please see your doc for a good evaluation. And BTW, good to see you have never engaged in tobacco use. Good for you.
