Background of the study: Cancer is a non-communicable disease that affects people without regard to race, gender, socio economic status or culture. It can occur at any site, tissue of the body and involves any type of cells. The reason for cancer is smoking and tobacco chewing hence they need education in order to prevent oral cancer

Approach: The research approach adopted for this study is an evaluative approach.

Design: The research design selected for this present study was pre-experimental

Setting: The study was conducted at selected areas of Bhandara city.

Participants: 50 adolescents were assessed by purposive sampling technique, as a non-probability sampling method.

Pre-assessment: The tool was developed by preparation of structured knowledge questionnaires content validity of the tool was established by giving to professional experts.

Intervention: Personal data was assessed by using a demographic questionnaire Structured knowledge questionnaire was administered on day one to 50 adolescents. Planned teaching programme was administered on the same day to them.

Post assessment: Structured knowledge questionnaire was administered after 7 days of administration of planned teaching programme to assess its effectiveness.

Results: The prior-test and after-test prevalence & rate of knowledge scores of subjects about the oral cancer& uses in regarding knowledge and attitude in adolescents revealed that pre-test (20%) subjects had less level knowledge, (62%) had medium level knowledge and (18%) had high level knowledge scores, where post-test (0%) subjects had low level knowledge, (0%) had medium level knowledge and (100%) had high level knowledge scores. Outcome of PTP was assessed with paired’ test and it was showed that there was significant increase in knowledge at 0.05 level of significance. In post-test knowledge score ranged from 21–27, whereas the pre-test knowledge scores ranged from 09-14. The mean post-test knowledge scores (χ² = 25.94) was apparently higher than the mean pre-test knowledge score (χ²= 9.54). The median of post-test knowledge score (M₂ = 25) was higher than the median of pre-test knowledge score (M₁ = 9). Calculated’ value (‘t’= 47.34, p< 0.001) is greater than table value, which represents the significant gain in knowledge, through the Planned Teaching Programme. Hence the hypothesis H1 was accepted. Thus it suggests that the PTP has been effective in increasing the knowledge of adolescents about oral cancer and its prevention. The association of the knowledge scores of oral cancer with their selected socio-demographic variables shows that, there is a no statistical significant relationship between gain in knowledge and personal characteristics like age, marital status, Professional Education, experience, area of work. Hence the hypothesis (H₂) rejected.

Interpretation and Conclusion: The study concluded that the PTP on skin ulcer and its prevention was an effective method for providing moderate to adequate knowledge and help adolescents to enhance their knowledge to provide information to have best healthy health habits.

Implications for clinical practices: On the basis of findings, it is recommended that a similar study may be replicated issuing a large number of respondents. It is also recommended that the other methods of teaching with frequent reinforcement be implemented for improving the knowledge of oral cancer and its prevention.
