AI beats doctors at detecting early stage of cervical cancer:UPSC

Artificial intelligence may be poised to wipe out cervical cancer, after a study showed that computer algorithms can detect pre-cancerous lesions far better than trained experts or conventional screening tests.

Background:

According to the World Health Organization, cervical cancer is the fourth most frequent cancer in women with an estimated 570,000 new cases globally in 2018.Some 266,000 women died of cervical cancer globally in 2012, 90% of them in low-and middle-income nations, according to the WHO.

Key Facts:

  • Cervical cancer is now a disease of poverty, of low resources.
  • A Scientist team has developed a computer algorithm that can analyze digital images of a woman’s cervix and accurately identify precancerous changes that require medical attention.
  • This artificial intelligence (AI) approach, called automated visual evaluation, has the potential to revolutionize cervical cancer screening.
  • The study began in the 1990s, involving more than 9,400 women who were followed for up to 18 years.
  • The AI technique, called automated visual evaluation, found precancerous cells with 91% accuracy, according to a report published in the Journal of the National Cancer Institute.

Significance:

  • The goal is to roll out the technology in the next three to five years, enrolling more patients in clinical trials worldwide and eventually making it easily accessible everywhere.
  • The aim is to keep costs very low so that women most in need can benefit.
  • This could really cut down on a lot of missed cases of cervical cancer, and allow more patients access to diagnosis and treatment.
