Hi!
It is a lot to deal with and I think so many of us struggle with the idea of these risks even without pre-existing health anxiety so that must make it extra hard.
This paper talks about the risks, as well as getting the best effect from biologics (minimizing antibodies by combining with an immunomodulator, monitoring antibody and drug levels)
Here's the bit about risks for anyone who doesn't want to read the whole thing:
"One of the biggest concerns with combination therapy is the potential for increased adverse outcomes, notably severe infection and malignancies. However, no incremental increase in the odds of serious infections was actually seen with any dual therapy combinations over monotherapy in a study querying the FDA Adverse Event Reporting System (FAERS) [Deepak et al. 2013]. It is more difficult to truly calculate the risk of lymphoma with combination therapy since most studies are not powered to detect this relatively rare event. A meta-analysis including 9 RCTs, 3 cohort studies and 14 case series with 66% of
patients concomitantly taking anti-TNFs and immunomodulators calculated a rate of non-Hodgkin’s lymphoma of 6.1 per 10,000 patient-years in patients taking combination therapy compared with a baseline 1.9 per 10,000 patient-years, with a standardized incidence ratio of 3.23 [Siegel et al. 2009]. In 2006, the FAERS was alerted to eight cases of the aggressive and usually fatal hepatosplenic T-cell lymphoma (HSTCL) associated with infliximab use in young patients receiving treatment for inflammatory bowel disease (IBD), prompting the FDA to add a boxed warning [Mackey et al. 2007]. Since then nearly 40 cases have been reported in CD patients, the majority occurring in young males (mean age at diagnosis was 30). Of the patients who were treated with anti-TNFs, 96% had been exposed to anti-metabolites [Selvaraj et al. 2013]. To date, no cases of HSTCL have been identified in patients on combination therapy with MTX."
There are certainly people on the forum who have been on Remicade for 10 years - but concomitant use of an immunomodulator greatly increases the chance of being able to stay on a biologic for a longer time. See this paper

Hope those papers help you and pursuing some treatment for anxiety sound really positive too
Lots of luck! :ghug:
