AnPac Bio Study Shows Strong Correlation between CDA Score and Risk of Cancer and Diseases - Large Population Screening Study Reached Key Milestone with Over 2,000 Confirmed Cases Philadelphia, PA

AnPac Bio Study Shows Strong Correlation between CDA Score and Risk

of Cancer and Diseases

Philadelphia, PA, October 4, 2021 - AnPac Bio-Medical Science

Co., Ltd. (Nasdaq:ANPC, "AnPac Bio," the "Company" or "we"), a biotechnology company with operations

in China and the United States focused on early cancer screening and detection, announced today it has achieved a significant milestone

and positive result in its general population cancer risk assessment tests and subsequent follow-up study on enrolled individuals whom

obtained further check-ups and diagnosis at healthcare providers using their cancer and disease diagnostic tools. As of September 30,

2021, healthcare providers have confirmed 2,067 cancer, pre-cancer, and disease cases, which includes 22 identified types of cancer, 25

identified types of pre-cancer, and multiple other related diseases. An initial analysis showed that confirmed cases are strongly correlated

to CDA test score, confirming that the CDA test is an effective method to initially screen the population for risks associated with cancer.

AnPac Bio's follow-up study involved (a) enrolling high, medium,

and low risk groups of individuals based on their CDA test scores following CDA testing of a large, asymptomatic population, (b) recommending

enrolled individuals to obtain follow-up check-ups at healthcare providers, (c) following up with enrolled individuals via phone interviews,

and (d) analyzing interview results and data. As of September 30, 2021, 14,806 individuals in the high, medium and low risk groups were

contacted and interviewed, and 2,067 individuals were confirmed as cancer, pre-cancer or other disease patients. Based on an initial analysis

of the most recent follow-up data and results, CDA technology is an effective initial screening tool for asymptomatic general population

for multiple cancer types, pre-cancer types and other related diseases. The confirmed cancer and pre-cancer cases detected 22 types of

cancer and 25 types of pre-cancer, including esophageal cancer and thyroid cancers that currently lack effective biomarkers for early

screening and detection.

The top five confirmed cancer types and pre-cancer types are as follows:

The above data demonstrates that CDA technology is also very effective

in finding pre-cancer diseases as confirmed pre-cancer cases are much higher than those of confirmed cancer cases, which is very attractive

and meaningful for cancer prevention. However, the confirmed cases are highly likely to be under-reported because (a) only cases from

individuals that we were able to successfully contact are recorded, (b) some enrolled subjects did not give full final diagnosis results

when contacted, and (c) as an on-going follow-up study, more confirmed cases will likely be developed and recorded over time.

Developing a viable pre-cancer and early-stage cancer screening technology

is critical to detect cancer early and to save patient lives. However, its development and progress has been relatively slow, despite

decades of heavy investments and efforts by leading scientists and research groups. One of the key factors has been the lack of leading

detection experts to develop sensitive technologies for low level signal collection and processing. AnPac Bio has built a unique team

of physicists, and experts with extensive experience from semiconductor and AI-based computational analysis to build the unique CDA technology

Over the past 12 years, AnPac Bio's team has innovated and

developed biophysics-based detection technology, in which biophysical properties of blood are detected and analyzed for early-stage

cancer screening and detection. The Company has been a staunch champion of the concept of multi-cancer detection through developing

its CDA technology. The measurement of biophysical properties for cancer detection can detect multiple cancer types earlier, more

cost effectively, with higher sensitivity and specificity, and through relatively simple sample requirements and test procedures.

These features make AnPac Bio's CDA technology perfectly suited for screening general population for cancer affordably.

Dr. Chris Yu, CEO and Chairman of AnPac Bio commented: "We are

very pleased to reach the milestone of confirming over 2,000 cases and to achieve significant validation of CDA technology for general

population cancer and pre-cancer risk assessment. This is truly a breakthrough technology in catching multiple cancer and pre-cancer types

earlier to prevent cancer and provide better patient outcomes. We are very proud of our contributions to the battle against cancer and

we are contributing to save lives now. We are already making a significant impact in the fight again cancer through our innovative ideas

(multi-cancer detection), technology development and finding potential cancer and pre-cancer earlier on a daily basis. We believe our

CDA technology's results speak for themselves and expect that public health agencies and organizations seeking the most promising

tools for detecting cancer and pre-cancer earlier will look closely at AnPac Bio."

AnPac Bio is a biotechnology company focused on early cancer screening

and detection, with 148 issued patents as of June 30, 2021. With one CLIA and CAP registered clinical laboratory in the United States

and two certified clinical laboratories in China, AnPac Bio performs a suite of cancer screening and detection tests, including CDA (Cancer

Differentiation Analysis), biochemical, immunological and genomics tests. According to a Frost & Sullivan's report issued in

2020, AnPac Bio ranked third worldwide among companies offering next-generation early cancer screening and detection technologies in terms

of the number of clinical samples for cancer screening and detection in 2019. The Company has a significant cancer screening and detection

database consisting of approximately 43,900 clinical samples as of March 31, 2021. AnPac Bio's CDA technology platform has been

shown in retrospective validation studies to be able to detect the risk of over 20 different cancer types with high sensitivity and specificity.
