Tiredness (fatigue) is probably the most common side effect of breast cancer treatment. It’s fairly common for fatigue to last for months after treatment is over. For some people, it may last for a year or two. Some women taking hormonal therapies, which are given for several years, find the tiredness continues while they are taking the treatment.
If you have fatigue you may:
- feel that you have got no energy and could spend whole days in bed
- feel as if everyday activities like showering or cooking can seem impossible and have problems doing even small chores
- have difficulty concentrating or thinking clearly, making decisions and remembering things
- feel breathless or light-headed after very little effort
- have sleep problems
- lose interest in sex
- feel more emotional than usual.
Fatigue can affect the way you think and feel. Even things you usually enjoy, such as reading or watching TV, can be difficult.
You may find fatigue affects your relationships and makes you impatient with people around you. Some people end up avoiding socialising because it’s too much effort.
