[thurz]

My husband was treated for superficial bladder cancer 18 months
ago and was told it did not go outside the lining.His follow up visits were every 3 months.Since then he had back problems and had MRI and Cat Scan done, Drs. have discovered a 1.9 cm shadow
in the lymph nodes in L3 and was told not anything can be done , just provide quality of life. Also lumps has appeared in the grion area since the L3 lymph nodes. Question , what are the symtoms and cause .What can or cannot be done.We are desperate to have more knowledge and alternate medical advice on alternate drug altenatives. Please help our family with any information you can provide.
