dee, not trying to scare you (as this is not relevant to you) but Sqad needs to understand that not all breast cancers can be felt externally. my friend is recovering from breast cancer that was found at a routine mammogram, and no amount of experienced prodding would have found it. personally, I've been to the breast clinic with a breast lump I've found, and an ultrasound scan has discovered others which even the specialists had checked for in examinations.
any lump needs to be checked with a GP. and when you're of a "certain age" you must attend mammograms when you are called.
