Hello, Vera

Bet you didn't know aloe vera could cure cancer.
Aloe Vera is a natural plant. The form you buy may be nearly 100 per cent natural. This natural compound was used in Egyptian times to fight skin problems and as a cancer treatment particularly for skin cancer, and one of its major benefits is its ability to soothe. It contains at least 6 natural ingredients which act as ´anti-inflammatory agents´, reducing inflammation, one of the important precursors to cancer.
Aloe vera can fight cancer.
What criteria is used for "100% natural"? What devilishe moderne practice has been used to defile the pure aloe vera, so it's not quite there? Never mind.

I wait with bated breath for the stunning evidence of aloe's amazing cancer-fighting properties, but none seem to appear. How strange. Just lots and lots of sciencey-sounding waffle.

It doesn't help, either, when the official Cancer Research site publishes stuff like  this:
Some people claim that aloe vera can balance the immune system, or even treat and cure cancer. Studies have been carried out into this and some laboratory studies and early studies on animals seem to show that extracts from aloe may be helpful in boosting the immune system to attack cancer cells.
It goes on to cite, fairly credulously, a study that claims to show aloe vera shrinking cancer cells:
One study in Italy of 240 patients reported in 2009. It tested aloe vera alongside chemotherapy for people with metastatic lung cancer, bowel cancer, and stomach cancer...
...In this study the cancer was controlled or shrank for a time in 67% of patients who had the combined aloe and chemotherapy treatment and in 50% of patients who had chemotherapy alone. In this study the researchers said that patients taking the aloe vera had a better quality of life and that they had fewer chemotherapy side effects such as numb fingers and fatigue. They also said that there were no ill effects from the aloe vera. More patients who had the aloe vera survived for 3 years than patients who just had chemotherapy.
Now, I'll give Cancer Research its due. It also points out that
Although this research seems positive the researchers said that there are some concerns about the study. The researchers knew which patients were receiving aloe vera and they may have influenced the results.  
Admittedly, they're only showing the criticisms the researchers themselves apparently brought up, and seem to have no thoughts on the study. But they also state:
But there is no evidence that aloe can treat cancer in humans. Some types of aloe can cause severe side effects when used as a cancer treatment and should only be used under medical supervision. It should never be used instead of conventional cancer treatment.
We don't recommend alternative therapies in place of conventional treatment because there is often little (if any) scientific or medical evidence to back up the claims made for these therapies. If you have cancer, using methods such as aloe vera instead of conventional medical treatment can be very harmful to your health.
The trouble is, the damage is already done by the earlier statements that show some lukewarm support for at least the idea of aloe vera as a cure for cancer. You end up with sites like thealoeverasite.com able to spew up garbage like this:
So popular is the idea that Aloe Vera may be able to treat Cancer that Cancer Research UK have devoted an internet page to it in which they generally state that there is no scientific proof but that it can do no halm (sic).
This is dodging the truth by any standards, as Cancer Research make it quite plain that very serious "halm" can come from trying to treat cancer with aloe vera.

I can quite understand that the possibility of aloe vera being a miracle cure for cancer would be of great interest to Cancer Research, for very legitimate and understandable reasons. Hell, I'd probably shout it from the rooftops. But the science shows nothing of the sort. In fact, a literature review from the University of Westminster concluded that
There is no evidence from clinical trials to suggest that topical Aloe vera is effective in preventing or minimising radiation-induced skin reactions in cancer patients.
But this doesn't stop hundreds of altie sites heaving up their unfounded claims for aloe's alleged properties for treating and preventing cancer itself - and of course, selling you their crank remedies.
