Helen my Onc told me I'd gain a lot of weight and likely not lose it on steroids before I began chemo, in truth I lost a stone I could'nt afford to as was alreay quite skinny and petitte !
Nothing I have ever read has related weight gain to cancer progression at all and think this is usual for steroids and this lady may be having the reaction I had.
My hubbys younger brother has always had bad asthma and in some of his childhood pics he looks like the Michelin man from ther steroids he was taking but as an adult is vey thin so I do think we all are different in how we react to them.
