Detailed explanation-1: -As a young mother, Henrietta Lacks and her husband were raising five children near Baltimore when she fell ill. She went to Johns Hopkins after experiencing extensive vaginal bleeding and was diagnosed with cervical cancer. Despite treatment, it cut her life short on 4 October 1951. She was only 31 years old.

Detailed explanation-2: -Viral multiplication in a stable strain of human malignant epithelial cells (strain HeLa) derived from an epidermoid carcinoma of the cervix.” Journal of Experimental Medicine 97 (1953): 695–710.

Detailed explanation-3: -In the early 1980s, German virologist Harald zur Hausen found that HeLa cells contained multiple copies of human papillomavirus 18 (HPV-18), a strain of HPV later found to cause the type of cervical cancer that killed Lacks.

Detailed explanation-4: -Sometime around the birth of her fifth child at age 31, Henrietta Lacks was diagnosed with cervical cancer, which would take her life that same year.

Detailed explanation-5: -She died in 1951, aged 31, of an aggressive cervical cancer. Months earlier, doctors at the Johns Hopkins Hospital in Baltimore, Maryland, had taken samples of her cancerous cells while diagnosing and treating the disease. They gave some of that tissue to a researcher without Lacks’s knowledge or consent.
