Skin cancer is a high-risk disease in the United States, with 5 million people diagnosed with it every year. The US health system spends $8 billion on this, and more than 100,000 of the 5 million people are skin cancers. The highest rate of melanoma in the world, it kills more than 9,000 lives every year, and this number is still rising year by year.
Looking around the world, melanoma is also a major enemy of public health. In Australia, there are more than 13,000 new melanoma patients each year, and the number of deaths is 1600 per year (the Australian population is very small). In Europe, melanoma kills 20,000 people every year.
In order to curb the rising mortality of melanoma, medical experts need to race against time to diagnose the type of skin cancer in patients as early as possible. The data shows that if the symptoms can be detected in time, the patient's chance of survival in five years is over 98%. However, once cancer cells spread to the patient's lymphatic system, the chances of survival immediately fall below 16%.
The development of technology has provided doctors with very effective tools. Today's professional dermatologists can use early imaging techniques called Dermoscopy to detect melanoma early, but this approach still faces two major challenges.
First of all, the number of professional doctors who can master such technologies in the medical community is seriously inadequate, so patients in many remote areas will be delayed. How to make such diagnostic methods normal and cheap is the biggest challenge in the medical world today.
Secondly, people are not sages, they can't be ignorant, and misdiagnosis in the diagnosis process is a common occurrence. The data show that to diagnose a case of melanoma, at least nine surgical biopsy is required. Surgery biopsy not only causes great physical pain to the patient, but also wastes a lot of money.
Therefore, in response to these two challenges, the medical community needs to intensify innovation to improve the accuracy of melanoma diagnosis. Since the development of human medicine, blood tests have been one of the effective ways, and this method is fast and convenient. The general practitioner can complete the inspection work in a local medical institution or laboratory with simple training. After the test is completed, the data can be an important reference for the attending physician to issue a diagnosis notice. Unfortunately, there is no reliable blood test for melanoma in the medical community today.
