Paul Davies Quotes

Cancer essentially lives in us and becomes activated at some point, and then cells begin to psychotically divide. Initially, the cancer cell looks like other cells and the body invites it in.

I was working with stem cells as part of a NASA programme. We realised that the science of stem-cell proliferation was also fundamental to cancer cells when cancer enters the phase of metastasis.

Cancer cells have a lot of other things that are really wrong with them, and we should never forget that these are cells that have become deaf to all the signals that the body sends out, such as you can multiply a certain amount, you can be in a certain place in the body, where to stay, where to move, and so on.

What we discovered, counter-intuitively, is that when you start killing a cancer cell, one of the things it does in order to survive is to spread even further. It causes itself to form new blood vessels. We've termed this 'reactionary angiogenesis.'

Cancer is not just a dividing cell. It's a complex disease: It invades, it metastasizes, it evades the immune system.

The bad news is that my thin melanoma has something called mitosis, which means the cancer cells are dividing and multiplying even as I write. My thin melanoma has already spread outside of the tumor and into the deep layers of skin.

The most dangerous cancer cells are actually the ones that are more like stem cells, which have this ability to produce themselves over and over again. More and more cancer biologists say stem-cell-like cells in cancers are the most dangerous.

Cancer cells have had so many other things go wrong with them, genetic, non-genetic changes, that those cells, one of the things they then get selected for is that they have lots of telomerase because now the telomeres in those cells get maintained.

Breast cancer is thought to use cholesterol to help the cancer migrate and invade more tissue.

It's not at all good when your cancer is 'palpable' from the outside. Especially when, as at this stage, they didn't even know where the primary source was. Carcinoma works cunningly from the inside out. Detection and treatment often work more slowly and gropingly, from the outside in.

My father, Simon Hoggart, was diagnosed with pancreatic cancer in June 2010. By this point, it had spread to his spleen and metastasised in his lungs and so was pronounced terminal.

Cancer has enormous diversity and behaves differently: it's highly mutable, the evolutionary principles are very complicated and often its capacity to be constantly mystifying comes as a big challenge.

This particular nurse said, Cancer cells are those which have forgotten how to die. I was so struck by this statement.

In general, all cancers have been traditionally characterized by the way they appear under the microscope and the organs in which they arise.

If you're unable to catch it in time, the cancer can spread to the lymph nodes and at that point, the cancer is essentially incurable, but that doesn't mean your condition can't be improved.

Cancer is really a DNA disease... We have these certain genes that prevent our cells from growing out of control at the expense of the body. And it's a pretty good, robust system. But if a couple of these genes fail, then that's when cancer starts, and cells start growing out of control.

A tumor often grows silently and doesn't start making itself known until it's pushing on structures or organs or tissues around it in a way that starts to mess up the whole system.

The idea that cancer genes are sitting inside each and every one of our chromosomes, just waiting to be corrupted or inactivated and thereby unleashing cancer, is, of course, one of the seminal ideas of oncology.

When my sister was diagnosed with cancer in 1989, her doctor told her that the cancer had probably been in her system for 10 years. By the time cancer's diagnosed, it's usually been around for quite a while.

We all know that the earlier cancer is detected the more successful treatment will be, and my cancer had spread to my ribs and that was a very fast-growing cancer.

Osteosarcoma sometimes takes a limb to check you out. The, if it like you, it takes the rest.

Down to their innate molecular core, cancer cells are hyperactive, survival-endowed, scrappy, fecund, inventive copies of ourselves.

Cancer was not disorganized chromosomal chaos. It was organized chromosomal chaos

Cancer is something that, tragically, affects almost all of our lives.

As long as we do not know how the cell works, we don't know the kind of havoc the AIDS virus creates in the cell.
