Hello there @Pictime, welcome to the forum at this worrying time. I’m really sorry to read you had concerns about bladder cancer which have gone on to be diagnosed as a type of blood cancer. What a lot to think about and I’m so glad you found the forum.
I won’t pretend I know what you can expect, living as I do with a different type of blood cancer called Polycythaemia vera ('PV'), plus as a fellow forum member I can’t offer medical advice anyway, but I see dear @Spangleystar has shared the great Blood Cancer UK information about MALT lymphoma which I would urge you to read.
The Macmillan information that @Spangleystar suggested is also really good, and their information about potential treatments is helpful: MALT lymphoma (NHL) | Macmillan Cancer Support
Lymphoma Action also have some great information for you: MALT lymphoma | Lymphoma Action
At this early stage after diagnosis it can really help to keep note of all your queries, big and small, no matter what comes up for you. You can take these notes to your appointments to ask your specialists.
You should be given the contact details of your own clinical nurse specialist (CNS), but in the meantime if you have any medical questions the lovely expert Blood Cancer UK nurses are at the end of the phone. Do consider giving them a call on 0808 2080 888.
I hope you don’t mind but I had a look around the forum and found a couple of threads where forum members have found out they have MALT lymphoma too, which may be of interest as there are some links to further information included: Suspicion of lymphoma and Recently Diagnosed and Stressed
If you’d like to reach out to others in any threads just pop an @ before someone’s username and they should get a notification. If you’d like to look further around the forum just use the search box at the top and I’m sure you’ll find others who can share their experiences.
May I just say I’m really sorry you’re in this position right now and to be very kind to yourself. Do lean on loved ones, and I’d say keeping busy in healthy ways between tests and results at this early stage might help alleviate some very understandable worries.
Do please keep us posted @Pictime.
