Greetings madam.
It's unfortunate that you are being suffering from
Breast cancer and on
Chemotherapy.
Nobody can prevent it until & otherwise detected by regular screening at Hospital / Breast Examination(either Self at home/ healthcare professional at hospital ).
So Don't worry & create yourself unwanted disturbance to your mind.
Just Relax & divert your activity apart from thinking about that as treatment process is going on & it take care of the condition.
Then now coming to your problem, all chemotherapy have those side effects & it's difficult to avoid that.
I would like you to follow certain instruction as home remedial measure which are as follows:
For increase sweat:
-> Have only
Cold shower while bath and avoid to the maximum a hot shower.
-> Maintain your personal hygiene & use proper soaps.
-> Excess Sweat are due to
hormonal fluctuations of medication & to avoid that drink plenty of water viz., minimum 8 glasses/ day preferably boiled water.
For Bad taste in mouth:
-> Eat things like Salads, boiled vegetable curry , fruits, Soups or what ever nutritious food you like more , which provide you energy for combating your problem & never starve to make condition worse.
-> To avoid
bad breath, i advice you to use mouthwash (containing
povidone iodine) 3 times/day. If that taste of mouthwash is not ok for you try out Mouthwash containing
Chlorhexidine.
-> Take other medication as prescribed by your doctor.
Hope i tried my best & helped you.
