I'm not from the medical field, but even w/ that, I can say that as far as medical issues go, there is nothing that this serial should be credited w/, given all the bloopers it has done from day 1.
For starters, when Sushma had her abortion and lied about her age, nobody in the hospital thought it worth checking on, or contacting her family? Then, few episodes later, they showed the hospital staff trying to move Padma into a special ward when general ward beds were available, and Sachin rescued the day. Fast forward to when Sushma was in hospital after being thrown down by Brij, and the docs started w/ the 'ma ya bachcha' choices to the Sharmas, which they presented to Pankaj later when he kidnapped Roshni.
This plot was the worst. Yeah, leukemea is a health issue, like all cancers, although some, like breast cancer, get highlighted more than others like prostrate or pancreatic cancer. And yeah, there are bone marrow donor banks & all that. In the meantime, on one hand, there is also stem cell research going on - both adult & umbilical, as well as cord blood. In the field of medical ethics, the latter is still a debated issue, but one issue that is pretty much settled is that it's totally unethical to produce a baby just for the sake of using it as an organ donor: for Christ's sake, it's not a car!!!
But the way the serial presented it was no better than 3rd rate serials like KZK or My Sister's Keeper - coming up w/ that bizzare recommendation to produce another baby w/ the same father of the patient. Having a new born baby donate anything - blood, organs, etc is a non-starter in medical ethics: no doc would ever suggest that. Here, a renowned doc does, and other docs associated w/ the story are either crooks, who can be bought off, or incompetant. The only good one I recall was the one who saved Sushma after that accident I mention above.
So no thanks to this serial for 'bringing this issue to light'
