Kimir, I really do feel for you! 😞
Hopefully you will get your appointment through quickly, and will be able to get the answers you need.
As for whether this means you have BC, the answer is no - not at this stage. The chest CT has obviously shown something in your breast which needs further explanation, which will be done with a specialist clinical exam, imaging ( mammogram and/or ultrasound), and possibly a biopsy if necessary. these tests will tell you what is going on in your breast. The chances are very very high that whatever is there is nothing to worry about. CT scans, like MRI scans are very sensitive, as in they pick up lots of things, but not very specific, as in they don't always show exactly what those things are. In order for those type of scans to be diagnostic and tell you exactly what is going on all sorts of other things have to happen too - for instance they need to be looking at your boobs not your chest, and there often needs to be 'contrast solutions' which need to be put into your veins to show up certain things. Mammograms and ultrasound are the best imaging for breast as they are both sensitive and specific for breast problems - anything suspected can then be confirmed with a biopsy.
I'm so sorry you don't have many supportive people around, this is a hard place to be at the best of times, but both the helpline here and the forums are a great source of support. Please know that you can come here and say whatever you need - I check in most days, and will always respond if you need some support. Take care. X
