2021 examples of Cancer in a sentence

Paradoxically, once established, natural selection actually favors the continued growth of cancer.
And when you have a population of fast-dividing cancer cells, if one of them acquires new mutations, which allow them to grow more quickly, acquire nutrients more successfully, invade the body, they'll be selected for by evolution.
That's why cancer is such a difficult disease to treat.
An amazing fact is that, given the right environment and the right nutrients, a cancer cell has the potential to go on growing forever.
However cancer is constrained by living inside our bodies, and its continued growth, its spreading through our bodies and eating away at our tissues, leads to the death of the cancer patient and also to the death of the cancer itself.
But that is where the Tasmanian devil cancer has acquired an absolutely amazing evolutionary adaptation.
And the answer came from studying the Tasmanian devil cancer's DNA.
That means that all of these cancers actually are the same cancer that arose once from one individual devil, that have broken free of that first devil's body and spread through the entire Tasmanian devil population.
But how can a cancer spread in a population?
We think that cancer cells actually come off the tumor, get into the saliva.
When the devil bites another devil, it actually physically implants living cancer cells into the next devil, so the tumor continues to grow.
So this Tasmanian devil cancer is perhaps the ultimate cancer.
It spreads through the population, has mutations that allow it to evade the immune system, and it's the only cancer that we know of that's threatening an entire species with extinction.
The vet diagnosed this as transmissible venereal tumor, a sexually transmitted cancer that affects dogs.
And just as the Tasmanian devil cancer is contagious through the spread of living cancer cells, so is this dog cancer.
But this dog cancer is quite remarkable, because it spread all around the world.
We also believe this cancer might be very old.
In fact, genetic profiling tells that it may be tens of thousands of years old, which means that this cancer may have first arisen from the cells of a wolf that lived alongside the Neanderthals.
This cancer is remarkable.
Well this is a question which fascinated Chester Southam, a cancer doctor in the 1950s.
Ad he decided to put this to the test by actually deliberately inoculating people with cancer from somebody else.
And this is a photograph of Dr. Southam in 1957 injecting cancer into a volunteer, who in this case was an inmate in Ohio State Penitentiary.
Most of the people that Dr. Southam injected did not go on to develop cancer from the injected cells.
So just finally, cancer is an inevitable outcome of the ability of our cells to divide and to adapt to their environments.
But that does not mean that we should give up hope in the fight against cancer.
In fact, I believe, given more knowledge of the complex evolutionary processes that drive cancer's growth, we can defeat cancer.
My personal aim is to defeat the Tasmanian devil cancer.
Let's prevent the Tasmanian devil from being the first animal to go extinct from cancer.
And she then spent a lot of time researching to find the best cancer center in the world to get her subsequent care.
She said, "The cancer center was wonderful.
