Welcome or welcome back my dear bloggers to my daily blogs. I hope you all are in great health and are having a blast of a day.

Even after a very troublesome global pandemic that shut down the whole world for a year or so, Cancer still remains the most incurable disease. So why, why is it so hard to cure cancer???

 Cancer initially arises when the cells of our body, which are completely normal, goes through some kind of mutations. And most of the time, our body takes care of it on the first hand. But still, some mutated cells allow cancerous cells to develop without any reaction or resistance. Cancers becomes almost incurable, if they are metastasized. Moreover,  cancer is not really a simple or linear disease. There are more than 100 different kinds of cancers and we do not have a simple one shot cure that can work for all of them, they are unique and so requires unique cures.

The treatment for most of the cases generally include removing the tumors by surgery and radiation and chemo therapy for killing these cancerous cells that are left behind. In many cases, these treatments are really effective which makes the patient cancer free, once treated.

But there are problems that we expect scientists to solve in order to tackle cancers. Firstly , we would need new and better ways of studying cancer. One of the common and dangerous things about these aggressive  tumors is that they can have many populations of a bit different cancerous cells surrounding them. For example, Gleoblastoma, aggressive brain tumors, can have as many as six different kinds of sub clones in one single patient. Also they can induce normal cells to form blood vessels that are needed to feed the tumors and remove the waste products. They are also known to attack our immune system to suppress its function that will result in the breakage of the  shield of our bodies towards various diseases. 

When they are bombarded with the help of treatments lime chemotherapy, some cancer cells may switch on their protective shields the attack by changing their gene expression. 

Well, the good news is that there is a good progress in this field. The average mortality rate for most types of cancer has dropped since the 1970s. We learn more and more every day.

So that was all for this blog. I hope you all learned some thing and liked it.
