What make cancer so incurable?
Answers: Because citizens are looking in the wrong place.
cancers are pretty curable. But usually its because we enjoy a hard time finding a drug that targets cancer cells specifically. For example, to execute bacterial cells we have to find something that only the microbes has, that human cells don't have so that it kill only the bacteria. To attack a virus, we have to find ways the virus replicates that are different from the means of access human cells replicate. A tumor cell is entirely human, only mutated. So we have a tough time picking out things that make tumor cells a target, but not regular cells. For example, chemotherapy kill ALL rapidly dividing cells so a lot of times the forgiving has to endure a lot of fruitless side effects to endure these treatments.
Another reason is sometimes cancers hold no screening tests, so people might be walking around with cancer and not even know it because they don't perceive sick. Sometimes people only notice they hold cancer once the disease has spread throughout their body. Now, we can cut out a small tumor that hasn't spread (usually).... but when the cancer has spread to several lymph nodes, and different sites in the body it become much harder. It soon becomes impossible to surgically cut out all the tumors.
There's alot of reasons... Source(s): 2nd yr pharmacy student
Hi Rimi. You have asked an excellent question. The answer is a bit complex, but I will try to present a clear explanation of it.
Next, you need to understand that no two cancer cell are exactly alike! Every cancer cell is genetically different from every other cell. So, a treatment that works on most of those cells, may not work on all of them.
Third, cancer cells are extremely modifiable. Many cancer treatments are effective at first - then the remaining cells change to the treatment and become "resistant" to that treatment.
cancer is "incurable" because it is actually hundreds of different diseases, with each tumor/cancer consisting of hundreds of billions of genetically different cell, all of which are highly adaptive to their changing (toxically treated) environment.
I hope this help you understand this difficult issue. Best wishes and good luck.
