Writing process There is a range of approaches that writers take to the task of writing. Each writer needs to find their own process and most describe it as more or less a struggle. Before the invention of photocopiers and electronic text storage, a writer's work had to be stored on paper, which meant it was very susceptible to fire in particular.
Talcum Powder and Cancer What is talcum powder? Talcum powder is made from talc, a mineral made up mainly of the elements magnesium, silicon, and oxygen.
As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping to prevent rashes. It is widely used in cosmetic products such as baby powder and adult body and facial powders, as well as in a number of other consumer products.
In its natural form, some talc contains asbestos, a substance known to cause cancers in and around the lungs when inhaled see Asbestos. All talcum products used in homes in the United States have been asbestos-free since the s.
Most concerns about a possible link between talcum powder and cancer have been focused on: Whether people who have long-term exposure to talc particles at work, such as talc miners, are at higher risk of lung cancer from breathing them in. Whether women who apply talcum powder regularly in the genital area have an increased risk of ovarian cancer.
Does talcum powder cause cancer? When talking about whether or not talcum powder is linked to cancer, it is important to distinguish between talc that contains asbestos and talc that is asbestos-free.
Talc that has asbestos is generally accepted as being able to cause cancer if it is inhaled. This type of talc is not used in modern consumer products.
The evidence about asbestos-free talc, which is still widely used, is less clear. Researchers use 2 main types of studies to try to figure out if a substance or exposure causes cancer.
In studies done in the lab, animals are exposed to a substance often in very large doses to see if it causes tumors or other health problems. Researchers might also expose normal cells in a lab dish to the substance to see if it causes the types of changes that are seen in cancer cells.
Another type of study looks at cancer rates in different groups of people. Such a study might compare the cancer rate in a group exposed to a substance to the rate in a group not exposed to it, or compare it to what the expected cancer rate would be in the general population.
But sometimes it can be hard to know what the results of these studies mean, because many other factors might affect the results. In most cases neither type of study provides enough evidence on its own, so researchers usually look at both lab-based and human and studies when trying to figure out if something causes cancer.
Studies in the lab Studies that exposed lab animals rats, mice, and hamsters to asbestos-free talc in various ways have had mixed results, with some showing tumor formation and others not finding any. Studies in people Ovarian cancer It has been suggested that talcum powder might cause cancer in the ovaries if the powder particles applied to the genital area or on sanitary napkins, diaphragms, or condoms were to travel through the vagina, uterus, and fallopian tubes to the ovary.
Many studies in women have looked at the possible link between talcum powder and cancer of the ovary. Findings have been mixed, with some studies reporting a slightly increased risk and some reporting no increase. Many case-control studies have found a small increase in risk.
One prospective cohort study, which would not have the same type of potential bias, has not found an increased risk. A second found a modest increase in risk of one type of ovarian cancer. For any individual woman, if there is an increased risk, the overall increase is likely to very be small.
Still, talc is widely used in many products, so it is important to determine if the increased risk is real. Research in this area continues. Lung cancer Some studies of talc miners and millers have suggested an increased risk of lung cancer and other respiratory diseases, while others have found no increase in lung cancer risk.
These studies have been complicated by the fact that talc in its natural form can contain varying amounts of asbestos and other minerals, unlike the purified talc in consumer products.
When working underground, miners can also be exposed to other substances that might affect lung cancer risk, such as radon.The University of Arizona (UA) is the flagship institution in the State of Arizona and offers graduate programs in more than areas of study.

There are always eyebrow-raising things people say to those with cancer and/or their families. Maybe not everyone would find each of the comments listed below to be offensive but they've been submitted by readers as ones they wish they hadn't heard. I like to revisit this topic every so often to allow people to post comments and add to the list.
