Tobacco use in any form (chewing or smoking) is the most important risk factor for oral cancer. IARC Monographs (2004).
Chewing betel quid, with or without tobacco, a habit particularly prevalent in Southern Asia, is identified as a strong risk factor for oral cancer. IARC Working Group (2004).

IRRC Monographs reported as following:
IRRC Monographs
*** Betel quid without added tobacco:
An increased risk of statistical (or borderline) significance associated with betel quid chewing without tobacco was reported from all case-control studies of cancer of the oral cavity that considered this after adjusting for smoking and/or alcohol intake.
*** Betel quid with added tobacco:
Significantly increased risks for cancer of the oral cavity associated with chewing betel quid with added tobacco were observed in all of the case-control studies that considered this.

ORAL CAVITY CANCER IN DEVELOPED AND IN DEVELOPINGCOUNTRIES: POPULATION-BASED INCIDENCE

The highest rates are observed in Pakistan, Brazil,India, and France. These rates were consistent with country-specific risk factors and prevalence.
In developing countries, people are exposed to a wider range of risk factors, starting at younger ages, and primary prevention measures and policies are needed. Awareness of health professionals must be improved to identify people at risk and target them for prevention and to minimize the conse-quences of oral cancer.

Betel quid chewing in rural Bangladesh
"At baseline, betel quid was chewed by 33.2% of the cohort (35.5% of men, 31.6% of women).
In a subsample in which we collected methods of use, 17.5% chewed it without tobacco and 82.5% chewed it with tobacco.

WHO pointed out "Noncommunicable diseases (NCDs) kill 41 million people each year, equivalent to 71% of all deaths globally." in its fact sheets.
fact sheets
As "Modifiable" behavioural risk factors, tobacco use, increase the risk of NCDs.
Tobacco accounts for over 7.2 million deaths every year (including from the effects of exposure to second-hand smoke), and is projected to increase markedly over the coming years.

WHO also pointed out "Tobacco kills up to half of its users...."
