All cancer is dangerous and potentially life threatening. But certain forms of cancer are deadlier than others. For these kinds of cancers, there is usually no cure so far discovered – medical, surgical or alternative – and if someone has this, doctors usually count their days in weeks and months.

But there are certain types of cancers from which one can recover more or less completely. Usually these cancers are associated with non-critical parts of the body; parts that could be surgically removed to contain the growth of cancer, and still keep the patient alive.

For life to be preserved, however, no metastasis or spread of the cancer should have occurred. If cancer occurs in a less important area, goes undetected and spreads to a critical area, that becomes life threatening again.

One of the least deadly cancers is probably breast cancer. Breasts are prone to tumorous growth, and sometimes these can turn cancerous. However, detected early, a simple surgery can cure breast cancer. If the patient is lucky, internal removal of tissues can remove the cancer; even in more drastic cases, where removal of a breast itself is required, the patient can still survive and lead a healthy life.

Vocal Chord or larynx cancer (or any cancer of the glotis, epiglotis etc) is also often not fatal. Surgical removal of the vocal chords etc may often cure the cancer completely. Although the resultant lifestyle is often discomforting, even difficult, at least the patient does not die. The patient may have vocal chords removed, and may have to use a voice box to talk for the rest of their lives. They may not have the power of smell, they may have to breath through a hole in their throat, and any little immersion in water can drown them. But the cancer can be completely cured.

Similarly for prostate cancer, which too can be completely cured by surgical removal of the prostate glands, if detected early.

However, cancers like brain cancers, lung cancers and especially blood cancer can almost never be cured.
