Hi @Leanne75 and welcome.
I too had breast conserving surgery first followed by chemo then single mastectomy and Lymphnode clearance, due to multi focal and multi centric cancer pathology after surgery, and then radiation.
I am still wearing my Berlei soft form but at the Beast Care nurses advice, I added some rice in the bottom of it to keep it down (I sewed a sausage shape holder out of polar fleece to hold the rice) , and removed some stuffing to make it the right size.
It does move a little in the soft Best and Less bras with the removable padding that I am using with it, but it is mostly very comfortable.
I just worry a bit though that the soft bra doesn't give my remaining side enough support, and am not sure if by wearing the soft form on one side is affecting my back at all as the weight is uneven.
I have yet to see my usual chiropractor to explore that issue.
I have a light weight prosthesis but have yet to find a bra that doesn't dig into the areas that I had the lymph nodes removed from, as they are still swollen after radiation.
I am seeing the lymphodema Occupational Therapist at my public hospital and they have suggested taping the areas, followed by a Lymphodema pressure bra. I am seeing them in two weeks to have that done and fitted.
The prosthesis itself is very comfortable to wear, which surprised me, it is just finding bras that are comfortable for me all day. The soft ones from Best and Less are not strong enough to hold the prosthesis up enough.
You can get self adhesive prosthesis that stick on your skin, they are a little more expensive and require special washing but allow you to wear normal bras, you might see if that suits you when the time comes.
I have adjusted to the look of the surgery side, but it does make some clothes sit lopsided if you don't wear a prosthesis of some sort, especially camisoles that I wear to bed, the shoulder strap on my remaining side keeps falling off. And I still go to cup the breast on the surgery side while washing in the shower, and get a slight jar of realisation when it isn't there, I guess that will wear off over time.
I am planning on reconstruction on my Plastic Surgeon's public list next year.
I will have DIEP flap reconstruction.
At present I am only considering a single breast reconstruction, but as I will only get one go at it, I am going to have another MRI before surgery to ensure that the remaining breast is cancer free.
Mammograms and multiple ultrasounds with multiple Doctors, after my diagnosis failed to identify the second 2.2cm lump in another quarter of my breast, and the DCIS near the main tumour, so I have no faith at all in mammograms or ultrasounds identifying cancer in my breasts.
My surgeon is certain that my left breast is clear - I also had an MRI before mastectomy and in the first surgery I had a bilateral reduction removing 150g of breast tissue from my remaining breast which was all clear of cancer in the pathology - and my Oncologist is sure that chemo and the Aromatase Inhibitors I am on should ensure that it is clear too.
But it is hard to take the risk.
There are challenges, aren't there?
I hope some of the tips people have given you here help you with your problems.
