Hi LKP-7 and a warm welcome to our forum, 

I am so sorry to hear that they have found something abnormal on your mum's yearly mammogram this year - it's good that she has been having these yearly mammograms and hopefully that means that whatever it is, it has hopefully been picked up early. It's hard not to worry or anticipate the worst but there could be a number of explanations for the thickened tissue and swollen lymph nodes and you will only know for sure once you have received these important biopsy results which could take a couple of weeks. Only 5 days to go now before her appointment which will hopefully shed some light on what is going on. 

So many members of our community will be able relate to what you accurately describe as "this fear of the unknown" and I hope that they will pop by and share their experiences with you as well as their outcomes. You're right to try and keep a positive mindset and try if you can to stay away from the temptation to look anything up on Google as this will make you feel even more anxious and won't give any reliable answers. Have a look at our helpful tips to help you cope while waiting for important news. These are great tips to help you take one day at a time until your appointment on the 11th. 

I am keeping everything tightly crossed for you that it all turns out to be nothing of concern,
