Hi , welcome to the forum 😊 I know your brain will be running riot now trying to work out what's going on but it's impossible to second guess, symptoms of breast cancer vary so much and only the breast clinic can tell you for certain and you've set the ball rolling there already which is good.
Try not to keep googling as you won't find the answers and it will only add to your anxiety, I know how stressful a time this is but keeping busy helps! Let us know how you get on Xx Jo
