Research objectives: * To evaluate the quality of life of patients before and after surgery for benign head tumors ( meningiomas) and malignant tumors at stage I, II and III, to assess whether it depends on the size of the tumor, type of tumor, malignancy and its location * evaluation of the independence of patients before and after surgery for head tumors at different stages of the disease - benign tumors (meningiomas) and malignant tumors in stage I, II and III, evaluation of what factors affected the different independence of patients * Multidimensional evaluation of perceived social support of patients before and after surgery for head cancers - benign ( meningiomas) and malignant tumors in stage I, II and III, taking into account three sources of support: significant person, family and friends Scientific (research) problems: \- What is the quality of life of patients before and after surgery for benign ( meningiomas) and malignant head cancers at stages I, II and III ? Is quality of life in patients with head cancer dependent on tumor size, malignancy, location or type of cancer ?
