"Sunshine" can replenish Yang Qi

There is a joke in the medical field that "if you live long enough, you will be approached by cancer"! Cancer is a nightmare for many people, and it has mercilessly taken away many lives.

We are exposed to sunlight every day, and there are more and more treatments for cancer in recent years, and there is even a method of using light to kill cancer.

I. The tumor disappeared in two months, and photodynamic therapy saved him who was at the end of his rope

Mr. Lin is a northeasterner who has been diagnosed with cancer three times at the age of 58. He was diagnosed with laryngeal cancer in 2012, a hypopharyngeal tumor in 2018, and early esophageal cancer in 2020 during a medical checkup.

Fortunately, he received effective treatment for the first two cancer detections, but his condition was not so optimistic for the third time. There were two lesions present in Mr. Lin's esophagus, 18 cm from the entrance and 25 cm from the incisors. Both locations could be surgically removed, but he would likely need to face a total laryngectomy organ stoma, which would make it difficult to ensure normal eating function in the future and would seriously affect his post-operative life.

However, he was also unable to undergo radiation therapy, as he had previously undergone proton-heavy ion radiation therapy for other cancers, and it was difficult to eradicate both lesions through chemotherapy. To survive or to have a quality of life? Mr. Lin was caught in a dilemma.

Mr. Lin went to hospitals in many regions of China and finally came to a local hospital in Guangzhou, where he was advised to use photodynamic therapy, which can preserve normal eating function without the need for open-heart surgery.

The only risk is that Mr. Lin's previous radiotherapy area of hypopharyngeal cancer and the area of esophageal cancer may overlap, and the problem of esophageal stricture may exist after the operation. After full communication, the family agreed to undergo photodynamic therapy.

One month after the end of the first treatment, the review results showed residual lesions at the incisors, and the family requested another treatment, even though there was a risk of esophageal atrophy. So the doctor performed a second treatment for Mr. Lin, and one month later the lesion disappeared on review, but the treatment site was narrowed. The good thing is that the condition improved after the expansion and the disease did not recur after six months of re-examination.

What is such an amazing treatment all about? Can cancer be cured with just a beam of light? Follow Ai to learn more about photodynamic therapy.

II. What is photodynamic therapy that can kill tumors with just one beam of light?

Photodynamics first appeared in 1900, a student of a German medical expert published a paper related to the effect of photodynamics on cell killing.

In 1904, Tappeiner found that the phenomenon of cell killing by photosensitizers combined with light was dependent and first proposed the concept of photodynamic effect to describe this phenomenon.

In 1907, Tappeiner confirmed that oxygen was the key substance for the toxicity of photodynamic therapy and that the presence of oxygen was required to have the photosensitizing effect. Thus began more than 100 years of human research into photodynamic therapy.

What is photodynamic therapy?

Photodynamic therapy is a new type of therapy that uses photosensitizers, light, and oxygen molecules to produce photodynamic reactions that selectively target malignant tumors, vascular lesions, and microbial infections.

After a period of metabolism, the photosensitizer will be retained in the tumor and lesion tissues, and then a specific light source will be used to irradiate the lesion to kill cancer cells without open surgery.

What are the advantages of photodynamic therapy?

1、Precise treatment

Photodynamic therapy is highly selective and can selectively kill tumor cells and proliferating active cells without causing harm to the surrounding normal tissues, which can effectively reduce the side effects of the treatment on the body and thus increase the possibility of repeated operations.

2、Low side effects

Clinically used photosensitizers can be metabolized quickly within the cells, which can be finished within 48 hours and will not accumulate in the body, thus bringing fewer side effects to the body.

3、Wide indications

Photodynamic therapy applies to tumors of the cavity, cavity, and body surface, including common cancers of the esophagus, cardia, nasopharynx, stomach, oral cavity, larynx, liver, cervical, breast, vagina, skin, etc.

In addition to cancer, photodynamic therapy can also be used to treat periodontal disease, acne, psoriasis, retinopathy, and atherosclerosis.

Ordinary people can also use sunlight everywhere to fight cancer.

From the perspective of Chinese medicine, sunlight is one of the ways to replenish yang energy, and researchers from the University of California, San Diego School of Medicine also found that the incidence of pancreatic cancer is highest in countries with the least amount of light. This is because people in high-latitude, often cloudy areas have difficulty getting enough vitamin D through sunlight exposure, which subsequently leads to an increased risk of pancreatic cancer.

In addition, sun exposure has these benefits

1. Strong bones

Sun exposure allows people to obtain vitamin D, which can promote the body's absorption and utilization of calcium and phosphorus, allowing normal calcification of bone tissue, which helps maintain healthy bones.

2、Strengthen muscles

The vitamin D obtained from the sun can make calcium contractions in the muscles and can play a role in the transmission of nerve impulses so that human muscle strength is enhanced.

3、Protect cardiovascularly

The infrared rays contained in the sunlight can play a role in making blood vessels dilate, which can help promote blood circulation and speed up metabolism, which can help regulate blood pressure and play a role in cardiovascular protection.

Although there are many benefits of sunbathing, there are also a lot of cautions when sunbathing, it is recommended to choose the time 9 to 10 am or 4 to 5 pm, it is generally recommended to sunbath the top of the head, back, limbs and hands and feet and other parts, it is best not to wear dark clothing, so that the skin is fully exposed to the sun, pay attention to each sunbathing time in about half an hour can be.

Photomedicine is an emerging discipline and photodynamic therapy also has great potential for tumor treatment, but for ordinary people, prevention should always be put in the first place. We hope everyone can adhere to good living habits, stay away from cancer-causing factors, and not have a relationship with cancer.
