Newbie with Questions about Surfing/Water

Hi @ShellSurfing Welcome to the forum.  I was diagnosed at the beginning of December, had a partial before Christmas and then back for a mastectomy after New Year.  I love the beach and the water and was really angry about missing Summer as I couldn't get back in the water until the all-clear from the surgeon, which didn't come until a few weeks ago.  Although I don't get to do it as much as I like, I also love SUPing and kayaking.  I haven't had a chance to get on a SUP since surgery but I was kayaking over Easter - just gentle water because I'm still getting my strength back on the affected side and I had to work out how to get on the kayak the first time, which must have looked hilarious to anyone watching.  I don't know how large you are (I'm a C-cup) but I haven't noticed any problem with being unbalanced.  I do have both an everyday silicon prosthesis which I only wear if I have to (I find bras very uncomfortable now due to the nerve damage under the arm), and a silicon swimming prosthesis.  The biggest thing with mobility is making sure that you do the exercises and follow up as soon as possible if you have any cording issues.  I waited a bit too long for that but after only one laser therapy treatment, I noticed an immediate improvement.  The other benefit with a specialist physio or exercise physiologist is that you should get an exercise program to strengthen the side of the mastectomy.  Apparently, this is important for not developing lymphoedema, as is warming up.  I can well understand the sense of freedom and peace that being on the water can give you and you will get back out there as soon as you are healed.
 
You will find out more about the type and extent of your cancer with the path report after surgery.  I can understand you thinking about taking the other breast off to avoid worrying about it but in my limited experience, you don't need to for balance - again, I'm speaking as someone who is not large-breasted.

You will find lots of information and support on this site as well as a few laughs.
