Hi there ...
Thank you for the question ....
Low Ig A Levels indicate Primary immunodeficiency .
The IgA antibodies in the secretions play a major role in protecting us from infections in these areas. IgG and IgM are also found in secretions but not in nearly the same amount as IgA. IgA present in these secretions is also termed secretory IgA. If human mucosal surfaces were spread out flat, they would cover an area equal to one and a half tennis courts, so the importance of IgA in protecting mucosal surfaces cannot be overstated.
As you have recurrent infections so Primary deficiency is highly likely not the advance cancer .
It would be ideal for you to consult Immunologist once please for proper advise .
Regards ***** ***** luck .
