For hundreds of years, Chinese calligraphers have used a plant-based ink to create beautiful messages and art. Now, one group reports in ACS Omega that this ink could noninvasively and effectively treat cancer cells that spread, or metastasize, to lymph nodes.

As cells leave a , they frequently make their way to lymph nodes, which are part of the immune system. In this case, the main treatment option is surgery, but this can result in complications. Photothermal therapy (PTT) is an emerging noninvasive treatment option in which nanomaterials are injected and accumulate in cancer cells. A laser heats up the nanomaterials, and this heat kills the cells. Many of these nanomaterials are expensive, difficult-to-make and toxic.

However, a traditional Chinese ink called Hu-Kaiwen ink (Hu-ink) has similar properties to the nanomaterials used in PTT. For example, they are the same color, and are both carbon-based and stable in water. So Wuli Yang and colleagues wanted to see if Hu-ink could be a good alternative material for PTT.

The researchers analyzed Hu-ink and found that it consists of nanoparticles and thin layers of carbon. When Hu-ink was heated with a laser, its temperature rose by 131 degrees Fahrenheit, much higher than current nanomaterials. Under PPT conditions, the Hu-ink killed cancer in a laboratory dish, but under normal conditions, the ink was non-toxic. This was also the scenario observed in mice with tumors. The researchers also noted that Hu-ink could act as a probe to locate tumors and metastases because it absorbs near-infrared light, which goes through skin.

Abstract
Finding a simple and effective strategy to eliminate tumor metastatic lymph nodes is highly desired in clinical tumor treatment. Herein, we reported a Chinese traditional ink (Hu-ink)-based treatment for photothermal therapy (PTT) of tumor metastatic lymph nodes. By simple dilution, stable Chinese traditional ink dispersion was obtained, which presents excellent photothermal effect because of its high absorption in near-infrared (NIR) region. Meanwhile, as revealed by staining and photoacoustic imaging, Hu-ink could transfer to nearby lymph nodes after directly injected into the primary tumors. Under the guidance of dual-modality mapping, the metastatic sentinel lymph nodes could be subsequently eliminated by NIR irradiation. The good biocompatibility of Hu-ink has also been verified by a series of experiments. Therefore, the Hu-ink-based treatment exhibits great potential for PTT of tumor metastatic lymph nodes in future clinical practice.

Another snippet of hope to treat (but not cure) some cancers from Cancer Inc ignoring what's already known.. sadly not to all.

The fact that Dr Clark's works have NOT been 'officially published' in any Medical Journal makes it ILLEGAL for the doc to even mention her work, let alone cure you with it! How does Cancer Inc prevents 'official publication' of cures so as to protect it's annual 1/3T$ Industry?

In the US in the mid 1980s, Dr Robert Good.. then leader in immunology, with the world's first bone marrow transplant, and with over 2000 medical research papers published, discovered the natural, diet-based, enzymatic cure for pancreatic cancer. He was refused publication in all Medical Journals. The Journals informed him that his cure 'doesn't fit in with the concepts of this time'.

In the UK, the 1939 UK Cancer, valid today(!!), Act PROHIBITS the publication of any cancer cure. It also PROHIBITS discussion of cancer cures among any persons apart from Reg. Med. Docs! In the UK.. I would be in trouble for this comment!

The cancer cures are in: Dr. Clark's protocols. also using her Zapper. Hoxey's herbs.. ("the quack who cured cancer". He was arrested over 100 times, more times than any other medical practitioner, but his Texan prosecutor subsequently became his attorney after Hoxey cured his brother of cancer)! Germany's ozone, (that cured Pres. Reagan's lung cancer).

Dr. Burzynsksi's secret formula in Texas. Drs. Beck and Rife. bio-resonance. Cannabis oil. Turmeric. Papaya leaf tea. Essiac, (check for original formula). Essiac that cured the terminal bone cancer in Sen Ted Kennedy's son in a month. Yew tip extract. Dr Clark advised to use as many of these as you can get hold of.

UK medical Herbalsits have essiac extract.(much more powerful than the original tea), Sunderandia, cannabis oil etc.

UK medical Herbalists have essiac extract.(much more powerful than the original tea), Sunderandia, cannabis oil etc.

Researching Dr Clark you'll come across vitriolic comments that Dr. Clark died of cancer. Even if she did, that does NOT invalidate her 60 years of science-backed work. Yes, Dr. Clark did die of cancer. In her mid eighties, she had her car brake-lines deliberately CUT, she crashed and broke her neck!! She suffered severe pain and was unable to continue testing for her work or on herself. She died of the rare myolemia cancer whose symptoms mimic a severe cold.
