Eye doctors can be the first ones to detect some cancers. An eye doctor can check for ocular melanoma, a rare form of melanoma but one that usually can’t be detected by looking in the mirror.25

How did HeLa cells become immortal?

3- HeLa cells are immortal, meaning they will divide again and again and again… This performance can be explained by the expression of an overactive telomerase that rebuilds telomeres after each division, preventing cellular aging and cellular senescence, and allowing perpetual divisions of the cells.

Can you smell death?

Living bacteria in the body, particularly in the bowels, play a major role in this decomposition process, or putrefaction. This decay produces a very potent odor. “Even within a half hour, you can smell death in the room,” he says. “It has a very distinct smell.”3

Diseases, such as some cancers, and conditions such as metabolic disorders, can cause a distinctive breath odor as a result of chemicals they produce. Chronic reflux of stomach acids (gastroesophageal reflux disease, or GERD) can be associated with bad breath.10

Can HeLa cells make you immortal?

Her cells had the ability to reproduce indefinitely, making “HeLa” the first line of immortal human cells. As a result, her cells have now outlived her and will continue to live until after her great grandchildren have died of old age. Researchers took advantage of this immortal line.
