I am receiving my treatment from Ironwood Cancer center in Phoenix, AZ. I'm 70 yr old female and I would call myself active as well. Before this diagnosis I was determined to lose my Covid weight and was either biking 7 miles, walking 3 miles or working out in the gym once a day. I did manage to lose 25 lbs prior to my birthday in June. That is when I started having night sweats and saw my MD in mid-August. She ordered lab which was abnormal and referred me to an MD at Ironwood. My oncologist ordered more labs, a neck to knee's CT with contrast and an bone marrow biopsy to determine my SMZL diagnosis. I contacted Mayo at that time for 2nd opinion, I was give a mid December appt. I started my Rituximab treatments on 10-14. My weight was continuing to drop but now seems to be stable. I took a 2 week Thanksgiving break and then started the treatments again on 11/29 and will end on 12/20. I do feel much better than I did when I originally started. the treatment. Some of that may be due to the fact that I have accepted the cancer diagnosis and trying to enjoy my life, 3 children and 4 grandchildren despite the diagnosis. I hope this information is helpful to you.
