Hi Bob,
Of all the things it can be, bc is the Least likely, but it’s totally right that you have been referred under the 2 week rule to get it properly checked out.
There’s no way round it, but waiting is stressful, so it can help to cope with the wait by keeping busy, carrying on as normal & avoid any googling of your symptoms as this will only create a shed load of anxiety for no good reason.
By far, most breast changes turn out Not to be bc.
If you want to, do let us know how you get on.
