Patients will be informed about the abdominal massage application; they will be informed that it should be applied twice a day for five days, 30 minutes after breakfast for 15 minutes and 30 minutes after dinner for 15 minutes. In order to make the massage application more understandable and effective, the abdominal massage application video to be created by the researcher will be shared with the patient and his/her family. After the fifth day of the Abdominal Massage application, patients will be evaluated for the last time with the Bristol Stool Consistency Scale (Appendix-2), Constipation Severity Scale (Appendix-3), Constipation Quality of Life Scale (Appendix-4) and Patient Monitoring and Control Form (Appendix-5).

Patients who were determined to have constipation as a result of the Bristol Stool Consistency Scale evaluation and assigned to the control group by randomization method will first be administered the Patient Identification Form (Appendix-1), Constipation Severity Scale (Appendix-3), Constipation Quality of Life Scale (Appendix-4), and Patient Monitoring and Control Form (Appendix-5). The researcher will provide information about the "Patient Follow-up and Control Form (Appendix-5)" and the patients will be followed up regularly for five days.

After five days of follow-up, the patients will be evaluated with the Bristol Stool Consistency Scale (Appendix-2), Constipation Severity Scale (Appendix-3), Constipation Quality of Life Scale (Appendix-4) and Patient Follow-up and Control Form (Appendix-5).

Abdominal massage is a massage technique performed with soft and rhythmic movements applied to the abdomen. Abdominal massage is an inexpensive, non-invasive, non-harmful, non-invasive method that can be applied by nurses for the treatment of constipation or by teaching the patient and his/her family. During the application of abdominal massage, effleurage (patting), abdominal effleurage , petrissage (kneading), abdominal petrissage maneuvers are applied.

This form was created by the researcher by reviewing the literature. The form included a total of 39 questions about the patient's current disease, descriptive characteristics, socio-demographic characteristics, chemotherapy cycle and regimen, medication use that may cause constipation, performance status score, appetite status, amount of fluid consumed daily, physical activity status, and food group consumed in the last week.

The Bristol Stool Consistency Scale was developed by Lewis et al. The form of the stool varies according to the transit time through the intestine. With this scale, the stool form is evaluated over seven different stool types. In the scale, 1 and 2 points are evaluated as "hard stool-constipation", 3, 4 and 5 points as "normal stool", 6 and 7 points as "soft-watery stool (diarrhea)".

The Constipation Severity Scale (CSS) was developed by Varma et al. in 2008. Its Turkish validity and reliability was performed by Kaya. The scale consists of 16 items to determine the frequency and intensity of defecation and difficulty/difficulty during defecation. The scale has 3 sub-dimensions: "fecal obstruction", "laziness of the large intestine" and "pain". The score that can be obtained from the fecal obstruction sub-dimension is between 0-28, the score that can be obtained from the large intestine sub-dimension is between 0-29, and the score that can be obtained from the pain sub-dimension is between 0-16. The lowest total score that can be obtained from the scale is 0 and the highest score is 73. A high score on the scale indicates that the symptoms are serious. Cronbach's alpha value of the original scale: 0.88-0.91; Cronbach's alpha of the Turkish scale: 0.92-0.93.

The scale, which was developed by Marquis et al. (2005), and validated and reliably analyzed in Turkish (2015), consists of a total of 28 items. This five-point Likert scale consists of 4 sections: 'Anxiety or Worry' (11 items), 'Physical Discomfort' (4 items), 'Psychosocial Discomfort' (8 items) and 'Satisfaction' (5 items). In the Constipation Quality of Life Scale, questions 18, 25, 26, 27 and 28 are reverse items and are calculated by reversing them. A minimum score of 28 and a maximum score of 140 is obtained from this scale. The Cronbach's alpha value of the scale is 0.96. A low total score indicates a high quality of life.
