Does anyone know if you can start a DMT with a Lung Cyst?

I’m meant to be starting my first dose of Kesimpta tomorrow. But I had to go for a X-ray on Friday for Latent TB, it was a roller coaster day at the hospital my poor bf came to support me and ended up just sat with me like wtf is happening now! Anyway I came away with a bag full of antibiotics and a cyst on my lung. Now it’s likely I’ll have to summon some telepathic powers to get in contact with my NHS Neurologist and find out if it’s safe to start MS treatment with my new cyst before my nurse arrives to administer my meds tomorrow. I trying my hardest not to panic, keep laughing and just take another curve ball but I’ve been waiting over a year for something to just feel like I have an ounce of control over my life again. Any advise on any of the above subjects would be very appreciated ? :)
