Dejene, PhDb,*  \nDear Editor,  \nEvery day, millions of new cancer cases are recorded, suggesting that the disease is increasingly threatening people all over the world. This deadly disease is projected to increase in prevalence by a factor of five. The Knudson two-hit hypothesis proposes that the inherent mutation serves as the first hit to agene, with a subsequent event serving as the second hit that causes cancer to develop. Many cases begin with the development of precancerous diseases. All clinical manifestations that carry the risk of cancer, including syndromes linked with a higher-thannormal risk of malignant transformation, are collectively referred to as ‘oral potentially malignant disorders’[1] . Bloom syndrome (BS), often called Bloom-Torre-Machacek syndrome after the researchers who discovered it, is one such oral potentially malignant disorders. People of European Jewish descent are adversely impacted from BS. The primary clinical hallmark of BS is short stature, and it is transmitted in an extremely rare autosomal recessive pattern[2] . The presence of a sun-sensitive, erythematous lesion on the face, an abundance of well-demarcated hyperpigmented and hypopigmented skin lesions anywhere on the body, and an increase in the number of bacterial infections related to immunodeficiency are all helpful diagnostic markers. Cancer, chronic lung disease and diabetes are some of the severe consequences of BS. Cancers of the normal forms and locations appear at unusually high and early rates. Many of the symptoms of BS result from the hypermutability of the cells that comprise the condition. Patients with BS are prone to the same types of  \naAMR and Nanotherapeutics Laboratory, Department of Pharmacology, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Sciences (SIMATS), Chennai, TamilNadu, India and bDepartment of Medical Microbiology and Immunology, Institute of Biomedical Sciences, College of Health Sciences, Mekelle University, Mekelle, Ethiopia  \nThis manuscript has been peer reviewed.  \nSponsorships or competing interests that maybe relevant to content are disclosed atthe end of this article.  \n*Corresponding author.

The current BS population has a mean age of 18 years (range: 4–37 years) . In the BS population, cancer often presents at age 20 years (range: 4–44 years), with a proportion of 1:40 men to every woman, making men more susceptible to BS. Ashkenazi Jews, non-Jewish Semites, Japanese, Western European Christians and African-Americans are few of the ethnic groups and races that have been shown to have BS.
