| It is not obvious for the curative effect of the three major tumor therapies. |
Countries in the world medical profession still have no effective means of tumor therapy. Currently, the main ways of treatment are: surgery, chemotherapy and radiotherapy, each of which has its own limitation. |
| Surgery |
In medical profession of all countries in the world, surgical resection with primary lesions is the primary method of tumor treatment.
1．
85% of patients who are detected as tumor patients are already advanced. After the primary tumor is resected, the proliferation metastases will grow rapidly. * Note
2．
This gives the dying patient another hard attack, making recovery period even longer.
3．
It depends largely on the quality of doctors and medical equipment; With different medical environment, the outcome of the surgery will also be different.
And there will be enormous difference with different medical environment for the outcome of the surgery. |
| CT |
SPECT-CT |
 |
 |
| *
Note: the image contrast of irradiation of advanced tumor by CT and SPECT-CT in the same period. The CT diagnostic image shows that the surgery has only resected the original lesion; the SPCET-CT diagnostic image of the same period shows extensive tumor metastasis after surgery. |
| Chemotherapy |
Currently, it is most widely used after surgery of resection of original lesion.
1．
Different drugs are for different tumors. At present, there is no clear identification of effective drugs for certain kinds of tumors.
2．
There is no large difference in the sensitivity between tumor cells and normal cells, and the normal cells will also be wounded after chemotherapy, resulting severe side effect, which will cause serious poisonous side effects to human body.
3．
To reduce side effects of chemotherapy, physicians lower the dosage of drugs, which makes the treatment effect less obvious. |
| Traditional Radiotherapy |
Based on the sensitivity of tumor cells to make radiotherapy to the focus of infection.
1．
Currently, most radiotherapy equipment do not meet the ”three precision” requirement, i.e. precise plan, precise positioning and precise irradiation; the equipment cannot kill the tumor cells effectively, depending heavily on technology and professional skills.
2．
Large dosage of radiation is absorbed by normal cells, causing harm to the human body. |
