The effect of power and publicity on all men is the aggravation of self, a sort of tumor that ends by killing the victim's sympathies.

I had a tumor removed from my skull - attached to my skull - it got pretty serious for a second. I was told some scary things from the doctors. It was definitely nothing to play with. It was one of those things that will change your outlook on life.

Unfortunately, my dad had a brain tumor, and my father-in-law passed away from leukemia, so I spend a lot of time on those two causes. I also tend to support military charities like Warrior Gateway, which helps guys transition from combat back into civilian life.

That's the trouble with being me. At this point, nobody gives a damn what my problem is. I could literally have a tumor on the side of my head and they'd be like, 'Yeah, big deal. I'd eat a tumor every morning for the kinda money you're pulling down.'

When people say there is a 'reason' for the depression, they insult the person who suffers, making it seem that those in agony are somehow at fault for not 'cheering up.' The fact is that those who suffer - and those who love them - are no more at fault for depression than a cancer patient is for a tumor.

Having the brain tumor, coming out of surgery and going through all of that, you're like, I am never going to feel the same and I have this new perspective on life. So much gratitude, life just feels like this enormous treasure. Then that kind of just falls away and you're back being grumpy about having an early morning meeting.

This is going to sound crazy, but there was a period of time where on TLC they would show those surgeries - like a woman had a 90-pound tumor, or they separated these twins. And my sister and I - she lived in Ohio when I lived in California - would watch them together on the phone.

I had to learn a lot about myself during the situation with my brain tumor.

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.

Too often you see someone fall, break a rib, go in to the doctor and discover a tumor.

I will forever be grateful to my oncologist for opening the door and saying, 'Damn it, the tumor's 10 percent bigger,' before he even said hello.

Where does my body end and an invader start? And cancer, a tumor, is something you grow out of your own tissue. How does that happen? Where does medical ability end and start?

If you sequence a cancerous tumor, you should be able to tailor the therapy according to the root cause of the cancer. But it has taken so long to do the sequencing - which also requires time to prepare the samples and interpret the deluge of data that comes out - that the patients are already undergoing therapy by the process if over.

Before cancer, I was obviously disconnected. I had a tumor the size of a mango inside me and didn't do anything about it. It wasn't like I didn't know something was wrong.

That's a tumor. It goes across my liver, up through my lungs, all the way around my heart. And when they were done trying to cut it out, nuke it out with radiation and chemotherapy it out, it left so much scar tissue that when I walk outside now in cold weather and take a deep breath, it feels like someone is stabbing me.

After the brain tumor happened, I realized I love acting, I've always loved it, I may never get a chance to do it again.

Cancer is like the common cold; there are so many different types. In the future we'll still have cancer, but we'll detect it very, very early, so that it won't kill anybody. We'll zap it at the molecular level decades before it grows into a tumor.

I went in for an operation to remove a brain tumor.

To look at the cross-section of any plan of a big city is to look at something like the section of a fibrous tumor.

Millions of people die every day. Everyone's got to go sometime. I've came by this particular tumor honestly. If you smoke, which I did for many years very heavily with occasional interruption, and if you use alcohol, you make yourself a candidate for it in your sixties.
