AIUI, you can get certain licences on a "self-declared " medical.
Basically, if you're fit to drive, you're fit to fly.
Acting responsibly and prudently, I'd suggest you do a bit of spadework and present the evidence to your GP. (unless GP is into Aeromedicine or Aviation, they're going to be very wary about putting their name to the unknown )
Highlight the important bits of the pertinent regs and make it easy for the medic to say, "I don't see a problem."
Of course, it all depends on your final objective,- If you are just looking to fly for leisure, a Microlight licence is a much shorter, easier course than the full PPL. It can be either fixed-wing (often indistinguishable from a "full- size" * aircraft ) or a flex-wing ("hang-glider" with a trike-pod with a pusher-engine underneath)
* Microlights are limited to two seats. A lot cheaper to maintain, etc. You can now , also, get a powered hang- glider with a minimal undercarriage, which doesn't even need a licence ur any airworthiness inspection. ,though you'd be very foolish to try teaching yourself!
Powered parachutes(Paramotors) (strap a fan on your back, powered by a strimmer-engine) is another lightly-regulated option.
If the Flex-wing Microlight appeals, there is a "SSDR" (Single-seat, De-regulated) option.
I think you'll find details on the BMAA (British Microlight Aircraft Association)
Moving up to a "full-size" aircraft, (Group A) Yes, you need to have a medical. then the choice is Permit -to - fly aircraft, (LAA) - Light Aircraft Association, Or, the full-fat, highly- regulated (did I say expensive?)
light aircraft on a full Certificate of Airworthiness.
If you aim to fly commercially, you could still co Microlight- group A- (PPL) -CPL. but, unless you'd be happy to settle for pleasure-flying , get a proper medical first.
Note! I am not a qualified pilot, but have been an enthusiast for many years and studied all the options and the costs involved. This post may well be worth what you paid for it!
Coincidentally, my first partner lost an ovary through Endometriosis It didn't stop her (eventually) going on to bear 3 children
...I was fortunate to have another wonderful relationship,she developed a small sore which turned out to be malignant. succsessfully excised . Good luck!
Hope this is some help.
PS. welcome to the Forum....most are friendly, helpful and tolerant. I like to think the odd few others can't help it.
