Genuine cancer cells are created by mutation of normal cells in the host, and have the property of invading (infiltrating) surrounding tissues and metastasizing to distant tissues. Then, it continues to multiply until the host is killed and self-destructs together with the host. On the other hand, cancer that does not take life is not built on something similar to cancer, that is, it does not grow into a real cancer.

If there are no symptoms and cancer is found during screening, doctors say that if it is removed early, there is a nearly 100% cure. But it's not a real cancer, it's a pseudo-cancer, so it doesn't matter at all if you don't cut it.

In the past, in the case of breast cancer, it was thought that cancer that penetrates the skin is a real cancer with metastasis, but does not spread to the surrounding area even if it pierces the skin. Skin penetration means that there is a similar cancer that has infiltrated but does not metastasize.

When uterine cancer or lung cancer infiltrates, uremia may occur or life may be lost due to suffocation. However, there are some that get better with radiation therapy or local surgery and do not metastasize, which are also similar cancers. Among the above malignant lymphomas, some types of cancer disappear when Helicobacter pylori is eradicated with antibiotics. Therefore, in this case, it is reasonable to call it chronic change or chronic inflammation, not cancer.

There are many similar cancers in which it is difficult to tell whether it is cancer or not even after it has grown to a reasonable degree. On the other hand, there are real cancers that suddenly appear ferocious. Also known as intermediate stage cancer. Although they are being screened regularly, it is called intermediate stage cancer because it develops abruptly before the next examination, that is, between examination and examination. Because this cancer is malignant, patients who develop it usually die soon after. (Makoto, 58-59p)
