Can Cannabis kill Cancer ?

For thousands of years people have used cannabis for recreational, ritualistic and medicinal purposes.
In the modern era, the latter property excites a lot of people, and there is no shortage of wild claims about the supposed medical benefits of the plant. Of all the claims, perhaps the most bold is the assertion that cannabis can cure cancer.
Astounding testimonials about cannabis and its derived products shrinking tumours or curing terminal cases are easy to find on the internet. But alluring as these stories are, they tend to be based on misunderstanding, wishful thinking or outright falsehood.
Let's start by asking what the medical efficacy might be. Contrary to what most people believe, medical uses of cannabis have been widely studied.
A 2017 review by the National Academy of Science looked at over 10,000 studies. They found evidence for some applications of cannabis, including managing chronic pain and spasms associated with multiple sclerosis.
There was also good evidence that tetrahydrocannabinol (THC), the main psychoactive ingredient in cannabis, can reduce the nausea caused by chemotherapy. Indeed, a synthetic form of THC, called dronabinol, has been prescribed for just this use for decades.
But, crucially, there is zero evidencethat cannabis has any curative or even helpful impact on cancer, despite enthusiastic claims to the contrary.
Why then is there such a gulf between public perception and scientific evidence? Part of this is misunderstanding. For example, an often aired claim is that high-dose THC kills cancer cells in a petri dish. This is true, but not very meaningful.
Killing cells in a dish is extremely easy; you can do so with anything from heat to bleach. But effective anti-cancer agents must be able to selectively kill cancer cells in the human body while sparing healthy ones.
The reality is that cannabis simply cannot do this.

It's natural, man
Other cannabis advocates are driven by ideological fixation, most often expressed in a sentiment that cannabis is "natural" and implicitly better than pharmacological drugs.
But this is a classic example of an "appeal to nature" argument, and thus rather dubious.
The term "natural" is somewhat vague. If we define natural to mean that which occurs without human intervention, the argument still doesn't hold.
Arsenic, plutonium and cyanide are also natural, yet it would be a poor strategy to binge on these substances.
The active compounds of many drugs are themselves discovered in plants, synthesised to control the dose and maximise efficacy.
We already have THC-derived medicines, but these do not cure cancer, and neither does cannabis.
Sadly, some cannabis advocates go further, claiming that cannabis's cancer-curing abilities are covered up by drug companies. This is abject nonsense. Such a conspiracy would be massive and would rapidly collapse.

"Hard nipples" - areola or nipple skin

Someone once wrote"... when i get really cold, or get goosebumbs all over my body, the whole things really scrunch up, like, my entire areola scrunches itself up into a wrinkled little mound. it looks really weird and ugly, and i haven't ever seen other people's breasts do it. what is wrong with my areola/nipples??" The answer: Well nothing is wrong. This is what my areola does too. It's a normal reaction to the coldness or to irritation / stimulation. The little muscles in the areola do a similar goosebump thing as your other skin can do. People often call this phenomenon "hard nipples". Also note that skin on areola has less feeling or sensation to it than other areas of your body. If the areola was very sensitive, then breastfeeding would probably be quite uncomfortable because the baby pulls and tugs it! The nipples are sensitive but the sensitivity changes with hormonal changes, such as occur at mestrual cycle or pregnancy. Also this v...

Mastectomy Drain Breast Cancer Treatment

The  purpose of drains after mastectomy  is to drain away the fluid that can gather in the armpit region or around the scar on the chest wall. Some people after mastectomy also find that fluid gathers around the shoulder blade area on their back - this seems more common if the muscle from the back has been used for  breast reconstruction  at the time the mastectomy was done. When mastectomy is done - and especially if the lymph nodes are removed from the axilla or armpit - then there is a lot of tissue fluid and lymph fluid left with no where to go. This fluid normally flows through the lymph channels but if they are cut then it can escape into the normal skin and muscle tissues. Your surgeon will place drains under your skin after mastectomy. These drains gather up the fluid and remove it to a bottle (or bottles) that you carry around with you. Some people use a  belt clip to attach the drain  to their waistband - making them more mobile. Others car...

Youngest Breast Cancer Survivor

  No one is immune to Breast Cancer.  A four-year-old Canadian Girl, Aleisha Hunter, is reported to be the youngest Breast Cancer survivor in the world. On that note, she is also the youngest woman to ever have a mastectomy. At the age of two, her mother found a lump in her daughter's breast and the doctors confirmed that it was a very rare form of breast cancer. According to the article, less than five percent of women will have to have invasive breast cancer surgery before the age of 40. Luckily, this type of cancer is very slow moving and slow growing. So, she was able to be treated without chemotherapy and harsh radiation that would have harmed her developing immune system. I hope that she continues to heal and will realize how strong and special she is one day when she is older. Aleisha, you are strong and a survivor of a disease that claims a number of lives daily. Women and men alike have been stricken by Breast Cancer, although they are usually much older....
