Quotes[edit]

A[edit]

The fact that the general incidence of leukemia has doubled in the last two decades may be due, partly, to the increasing use of x-rays for numerous purposes. The incidence of leukemia in doctors, who are likely to be so exposed, is twice that of the general public. In radiologists … the incidence is ten times greater. ~ Isaac Asimov
  • Growth for the sake of growth is the ideology of the cancer cell.
    • Edward Abbey, The Journey Home: Some Words in Defense of the American West. Plume: New York. 1991. Pg 183.
  • We "need" cancer because, by the very fact of its incurability, it makes all other diseases, however virulent, not cancer.
    • Gilbert Adair, journalist and film critic, "Under the Sign of Cancer," Myths and Memories, 1986.

  • Writer Perry Brass was diagnosed with prostate cancer in March 2016. Three months later he had a radical prostatectomy, removing his entire prostate. Brass, then 68, was lucky: He lives in New York City, home to top-notch doctors and a medical community more informed about LGBTQ health.
    “I’ve been a gay activist — and been out — so long that I took it for granted I could talk openly to my doctors,” he told NBC News. But even he was unprepared for the side effects.
    "Your sex drive can take a nosedive," Brass said, adding that prostate cancer can also lead to erectile dysfunction. "You’re experiencing ED, but that doesn’t mean you’re not experiencing sexual attraction," he said.
    About 20 percent of patients treated with radiation experience irradiated bowels, which can make receptive anal sex painful or even impossible. Treatment can also affect penis size, ability to ejaculate, experience of orgasm and urinary continence during sex. Brass’ said his sexual function was relatively good, but instead he struggled with incontinence for weeks — using as many as nine “pads” a day and staying within yards of a bathroom at all times.
  • A professor at the University of Minnesota School of Public Health, Rosser has received a $3 million grant from the National Cancer Institute to put together the first comprehensive rehabilitation program specifically for gay and bisexual men with prostate cancer. But he’s not just a researcher — he’s a survivor himself, diagnosed last year at age 59. And he’s keenly aware of how little information is available for men like him.
    “When my husband was diagnosed and had a radical prostatectomy, we reached out for help," Rosser said. "We were amazed to see how little was out there. I realized there were no studies, no research. It was a neglected area.”
    But it wasn’t institutionalized homophobia, Rosser stressed. “Our efforts were focused on battling HIV, keeping young men alive. Frankly the older guys were secondary.”
    When it comes to cancer, urologists and oncologists — even wives — are laser-focused on survival, according to Rosser. But he said when it comes to male patients, "studies show again and again that quality of life is equally important." And, he added, "a big part of quality of life is urinary continence and sexual function.”

  • In the United States, prostate cancer is the most commonly diagnosed non–skin cancer and the second leading cause of cancer death. The American Cancer Society estimates that 241 740 American men will be diagnosed with the disease and 28 170 men will die of it in 2012. Prostate cancer demographics have changed dramatically over the past 30 years.

  • Allington is generally thought to have been first to use liquid nitrogen, in 195017. He recognized that the properties of liquid nitrogen were very similar to those of liquid air and oxygen. After the Second World War, liquid nitrogen became freely available and was preferable to liquid oxygen with its explosive potential. He used a cotton swab for treating various benign lesions but poor heat transfer between swab and skin meant this method was insufficient for tumour treatment.
    The contribution of Dr Irving S Cooper to cryosurgery was immense. An American neurosurgeon based in New York, in 1913 he designed a liquid nitrogen probe that was capable of achieving temperatures of -196°C. With it he treated Parkinson's disease and other movement disorders by freezing the thalamus, in addition to previously inoperable brain tumours.

  • The rate of people dying from cancer in the United States seems to have dropped steadily for 25 years, a new study says, but disparities remain between the rich and the poor.
    The overall nationwide cancer death rate fell continuously from 1991 to 2016 by a total of 27%, according to a study by the American Cancer Society, published Tuesday in CA: A Cancer Journal for Clinicians.
    That translates to about 2.6 million fewer cancer deaths total than would have been expected if death rates stayed at their peak, which was seen in 1991, according to the study.
    "The continued decline in the cancer death rate over the past 25 years is really good news and was a little bit of a surprise, only because the other leading causes of death in the US are starting to flatten. So we've been wondering if that's going to happen for cancer as well, but so far it hasn't," said Rebecca Siegel, first author of the study and strategic director of surveillance information at the American Cancer Society.
  • "The racial gap in cancer mortality is continuing to narrow -- so it was that the cancer death rate in blacks was 33% higher than in whites in the mid-1990s, and the current data now indicate it's 14% higher -- so it's still higher, but the gap is narrowing, which is really good news," Siegel said.
    However, the data also revealed a potentially troubling trend: a growing gap in death rates based on wealth.
    "It was surprising to see that the disparities by socioeconomic status are actually widening," Siegel said. "Wealth causes differences in exposure to risk factors and also access to high-quality cancer prevention, early detection and treatment."
    For instance, between 2012 and 2016, the overall cancer death rate was about 20% higher among people living in the poorest counties in the United States compared with those in the most affluent counties -- and socioeconomic inequalities in cancer mortality widened over the past three decades overall, according to the study.

The air we breathe is laced with cancer-causing substances and is being officially classified as carcinogenic to humans, the World Health Organization's cancer agency said on Thursday. ~ Kate Kelland and Stephanie Nebehay
  • The air we breathe is laced with cancer-causing substances and is being officially classified as carcinogenic to humans, the World Health Organization's cancer agency said on Thursday.
    The International Agency for Research on Cancer (IARC) cited data indicating that in 2010, 223,000 deaths from lung cancer worldwide resulted from air pollution, and said there was also convincing evidence it increases the risk of bladder cancer. Depending on the level of exposure in different parts of the world, the risk was found to be similar to that of breathing in second-hand tobacco smoke, Kurt Straif, head of the agency's section that ranks carcinogens, told reporters in Geneva.

  • There is no devil mocking you. God didn’t give you cancer to punish you. Colon cancer has come to you through a combination of losing the genetic lottery, cosmic rays, and perhaps too much bacon in your younger days.

Even though IR is a well-known genotoxic agent and human carcinogen, it is also widely used to effectively diagnose and treat cancer (Little, 1999, 2000; Pollack et al., 2000; Roof et al., 2003; De Potter et al., 2006; Erven and Van Limbergen, 2007). Since 1902 when the first radiation-induced cancer was reported (Little, 2000, 2003), and almost 100 years after radiation was used for the first time to treat tumors (Gramegna, 1909), it still remains the number one diagnostic and treatment tool for the majority of cancers (Pollack et al., 2000; Roof et al., 2003; De Potter et al., 2006; Erven and Van Limbergen, 2007). ~ Matt Merrifield and Olga Kovalchuk

While modern cancer radiation therapy has led to increased patient survival rates, the risk of treatment-related deleterious effects, including secondary cancers, is becoming a growing clinical problem (Leone et al., 1999). Relatively recent findings suggest that even fairly low doses of IR, such as those used in diagnostic procedures (e.g., X-ray or computer tomography), can lead to the development of radiation-induced cancers (Preston-Martin et al., 1989; Doody et al., 2000; Liu et al., 2002; Brenner and Hall, 2004). This risk of developing secondary treatment-related cancers is even more pronounced in children and young adults who received either diagnostic or therapeutic exposure to IR (Hildreth et al., 1989; Infante-Rivard et al., 2000; Hall, 2002; Shu et al., 2002; Kleinerman, 2006).

Last year, Vice President Biden said that with a new moonshot, America can cure cancer. Last month, he worked with this Congress to give scientists at the National Institutes of Health the strongest resources they’ve had in over a decade. Tonight, I’m announcing a new national effort to get it done. And because he’s gone to the mat for all of us, on so many issues over the past forty years, I’m putting Joe in charge of Mission Control. ~ Barack Obama

Physically, however, the body is quite able to completely regenerate itself as it approaches old age. Indeed, a quite legitimate second puberty is possible, in which the male’s seed is youthfully strong and vital, and the woman’s womb is pliable and able to bear . . . Now, to some extent there is a connection between this innate, rarely observed second puberty and the development of cancer, in which growth is specifically apparent in an exaggerated manner. ~ Jane Roberts
  • The Porto Ricans (sic) are the dirtiest, laziest, most degenerate and thievish race of men ever to inhabit this sphere… I have done my best to further the process of extermination by killing off eight and transplanting cancer into several more… All physicians take delight in the abuse and torture of the unfortunate subjects.
