Encore is a free 8 week hydrotherapy course for breast cancer patients run across Australia except not Victoria.Each session involves a one hour seminar on topics of interest like lymphodema , Otis foundation (free holidays) , clothing and undergarments post mastectomy. Then you spend one hour doing hydrotherapy.ie 2 hours per week for 8 weeks.It also provides an opportunity to meet other breast cancer people and make new friends.
Another free program is a half day seminar called Look Good Feel Good which is for any type of cancer patient and discusses wigs and makeup with a wonderful bag of top quality cosmetics to take home.
Also you might like to investigate local breast cancer groups to provide support in your transition back to every day life.It helped me a lot to seeing local women I’d met at a local group carrying on normal daily activities in my community.
Re supplements I was recommended to take Krill Oil tablets by my oncologist for joint pain/ stiffness and like @Deanne I found a daily walk of one hour very helpful to my physical and emotional state.I also participated in a local gentle exercise class run in my community twice per week for an hour.
