Why is curing Cancer so difficult ?

Cancer is a disease in which abnormal cell division takes place. Cancer is very difficult to cure . Why you ask?Because Cancer is not like any other microbe. There are ways of killing Cancer like Chemotherapy, hormonal therapy and Radiation.

But they are never successful. These techniques can kill the cell but even if there is a single Cancer stem cell that is left over, It results into a completely new Cancer. Adding to that, Cancer usually has sub clones. If it is the brain, there'll be about 6 sub clones. And one cure that will work for a sub clone will not work for another.

Some Cancers have learnt to mutate and adapt themselves to defend them from Radiation. There are about 100 Cancers discovered so far.. and we do not have the magic bullet for them all. And how long do we have until these super bugs take over ? Not much, but there's good news. Scientists have worked day and night to be one step ahead of the microbes.

Prevention is better than cure !!

Hela Cells

Ever wonder whenever scientists work on finding a cure to certain diseases and need human cells for trials. Until the year 1950, all the lab-grown human cells for trails died within a few days.

 In the year 1951, Dr. George Gey received a strange looking tumor. It was dark-purplish. It was harvested from the patient Henrietta Lacks who was raised in a tobacco farm in Virginia, Scotland. Hence the name Hela.

Unlike normal cells, Hela had the power to multiply itself forever. A normal human cell multiplies 50 times before it dies. But Hela on the other hand had a special type of chromosome which does not allow the cell to die. Hela keeps multiplying and never stops. Soon that year, the whole world produced about 6 trillion Hela cells. Hela is used in labs to discover cures for diseases and its symptoms. Henrietta Lacks died in a few months after her tumor cells were harvested. Thanks to her, We have an unlimited source of lab-grown cells.

MISSION BIO GEEK

I am passionate about Biology. I live and breath bio. Since I was a kid, I had always dreamed of becoming a biologist. To lay foundation to that, I have launched Bio Geek,  I always googled stuff to find out and learn more cooler things in bio. Right now, I have so much information to share, but no one to listen.  Bio Geek will be very helpful to the viewers. Please support me and ask me questions.
