CANCER SCREENING

What factors cause cancer?

Normal cells have an equal rate of growth and death. However, the external influences due to genetic mechanisms, diseased cells will disrupt the inherent balance, reproduce and grow continuously without dying according to the normal cycle and turn into tumors (tumors) that cause cancer in organs.

Major causes of cancer:

  • Chemical factors: contaminated food, toxic substances, chemicals that cause genetic mutations.
  • Biological factors: human papillomavirus (HPV)
  • Genetic mutations: acquired and inherited
  • Acquired cancer: due to mutations occurring during survival and because cells are affected by chemical and biological factors…
  • Hereditary cancer: caused by a mutation inherited from one parent. Subsequent individuals have an average 50% risk of carrying cancer-causing gene mutations.

Who should be tested for genes that cause cancer?

  • People at high risk (chemical exposure, polluted living environment, long-term use of contaminated food, people with unhealthy living habits)
  • People living with HIV have risk factors such as having been infected with HPV (especially residual infection with high-risk strains such as 16,18,45,52…), Gonorrhea, Syphilis, and other infectious diseases caused by HIV viruses, other bacteria through blood, genital tract …
  • People whose parents or family members have had cancer

Test procedure and method

1. Sampling method: Take a venous blood sample with a specialized instrument. Take samples on-site or at the nearest medical facilities, depending on the customer’s specific conditions.

2. Screening test for viruses and bacteria co-infected: HIV, HPV, HBV, HCV, gonorrhea, syphilis…

Checking for biochemical, hematological, and immunological factors to screen for risk factors and as a basis for comparison with gene sequencing results.

– The hematological, biochemical, immunological, and screening tests for viral and bacterial agents are performed during the day.

3. Cancer screening test:

The gene sequencing assays are performed using 10x Genomics’ latest single-cell gene sequencing technology.
