This is a randomized controlled study to investigate the effect of arm message on the success of peripheral intravenous catheter insertion in breast cancer patients undergoing chemotherapy. There are two groups in our study (control group=30, experimental group=30). The investigator applied hand massage to patients in experimental group before peripheral intravenous catheter insertion. The investigators evaluated the succesfull peripheral catheter insertion time, anxiety level, and satisfaction level of the patients.

Introduction: Peripheral intravenous catheter (PIVK) placement becomes difficult in patients diagnosed with breast cancer who receive chemotherapy because vein visibility decreases.

Objective: The aim of this study is to determine the effect of arm massage applied to patients diagnosed with breast cancer receiving chemotherapy on the success of peripheral intravenous catheter placement.

Method: The study will conducted in a randomized controlled experimental type in an outpatient chemotherapy unit of a hospital.The sample of the study will consist of 60 patients who met the inclusion criteria (experimental group = 30, control group = 30). Patients in the experimental group will receive arm massage before peripheral intravenous catheter placement, while patients in the control group will receive no intervention. The time to successful catheter placement, patient anxiety, and satisfaction levels regarding the procedure will be recorded.

Inclusion Criteria:

• diagnosed as breast cancer,
• having had the first course of chemotherapy,
• patients who has 1,2 and 3 vein degree

Exclusion Criteria:

• More than 2 unsuccessful attempts at PICK placement,
• The individual wants to leave the study
