Cancer Diary: Vitamins and Cancer

 


Vitamin supplements are the easy-to-obtain, off-the-shelf, magic pills that keep us healthy, right? Well, actually, some vitamins and supplements have been associated with an increased risk of certain types of cancer when taken in high doses. Here are a few examples:

  1. Vitamin A (Retinoids): High doses of vitamin A supplements have been linked to an increased risk of lung cancer.

  2. Beta-Carotene: High doses of beta-carotene supplements have been associated with an increased risk of lung cancer, especially in smokers.

  3. Vitamin E: Some studies suggest that high doses of vitamin E supplements may increase the risk of prostate cancer.

  4. Folic Acid: Excessive intake of folic acid supplements may increase the risk of colon cancer.

  5. Selenium: High doses of selenium supplements have been linked to an increased risk of skin cancer.

It's important to note that these associations are based on studies involving high doses of supplements, not the vitamins obtained from a balanced diet. Always consult with a healthcare professional before taking any supplements, especially in high doses

Blog editor's note: As a memorial to Carl, and simply because it is truly needed, MSI Press is now hosting a web page, Carl's Cancer Compendium, as a one-stop starting point for all things cancer, to make it easier for those with cancer to find answers to questions that can otherwise take hours to track down on the Internet and/or from professionals. The CCC is expanded and updated weekly. As part of this effort, each week, on Monday, this blog will carry an informative, cancer-related story -- and be open to guest posts: Cancer Diary.

In Memoriam: Carl Don Leaver

  1948-2021 It is with great sadness that MSI Press notes the death of Carl Leaver, CEO of the Press and typesetter and graphic designer par excellence . Many authors have expressed not only condolences but also a sense of legacy from covers he designed that they love.  Here is his obituary: On August 16, 2021, Carl Don Leaver of San Juan Bautista passed into eternal rest. A forester with the US Forest Service in Idaho and Montana, he turned to nature photography while working in the Bitterroot National Forest. His photographs graced national magazine covers and on a weekly basis the local paper of Hamilton, MT, the Ravalli Republican. He later worked on photography projects for the US Army (AFEES) and taught photography at the New York Institute of Technology in Amman, Jordan. His final career change led him to computer graphics and publishing as co-owner of MSI Press LLC; his many typeset books and book covers have helped MSI Press authors win a large number of awards over t...

A Publisher's Conversation with Authors: Book Marketing vs Book Promotion

Image
It is Tuesday. Monday's madness is over, and Wednesday will take us over the hump, so Tuesday it is--for some serious discussion with authors. Tuesday talks mean to address authors in waiting and self-published authors who would like to go a more traditional route or who would at least like to take their steps with a publisher by their side.  Today's post looks at the difference between book marketing and book promotion, two terms that are frequently confused. Leading to the confusion is that some of the same activities are needed for both. In fact, good marketing is dependent upon good promotion. Perhaps the essential difference is that marketing focuses on sales, and promotion focuses on awareness --  noting that without awareness, sales generally do not happen. Book Marketing Book marketing includes promotion, sales, and increasing awareness of the availability of the book. It generally starts with a marketing plan that identifies the target audiences and selects marketing ...
