Women - Coping With Sex Hormone Symptoms
Some cancer treatments lower the levels of sex hormones in the body. Low levels of sex hormones can sometimes cause mood changes.
Hormones are natural substances made by the glands of our hormone (endocrine) system. They are carried around our body in our bloodstream.
The main male sex hormone is testosterone. The main female sex hormones are oestrogen and progesterone.
There is evidence that a drop in oestrogen levels can cause mood changes. This could be due to the cancer treatment, the , or both.
The causes of mood changes can be difficult to assess because many factors affect mood, especially when you have cancer. Cancer can make you feel anxious, sad, stressed or irritable at times.
Hormone related mood changes can include:
feeling anxious, panicky and irritable
feeling very sad, which for some people can develop into depression
mood swings - one minute feeling fine and the next feeling low, panicky, and very irritable or tearful
One way to help control hormonal symptoms is to take hormones to replace the ones your body is no longer producing. is an effective treatment for many women. But some treatments for breast cancer aim to either stop the body producing sex hormones, or block their action. If you are having these treatments, you can’t unfortunately take HRT.
Doctors don’t routinely recommend that you take HRT if you have a cancer, such as breast cancer. Even if you have finished treatment there is concern that HRT may increase the risk of cancer coming back. Talk to your specialist if you are finding it difficult to cope with your symptoms. They can explain the risks and benefits of HRT and if this is an option for you.
Talk to your doctor or nurse if you feel sad or anxious and are finding it difficult to cope.
Sadness and depression can be treated in different ways. These include counselling, cognitive behavioural therapy (CBT) and antidepressants.
There are also ways you can help yourself, such as:
eat well - avoid foods high in sugar and fat, as well as processed foods and too much alcohol
do relaxation or deep breathing exercises
take regular exercise that you enjoy, such as walking, swimming or yoga
avoid alcohol
get enough sleep – this can be difficult if you are feeling anxious or sad, but lack of sleep can make it harder to cope
get help to control other symptoms – if you don’t feel well it can make coping with mood changes more difficult
be kind to yourself – being harsh or over critical is not helpful and will make you feel worse
stay connected with family and friends
practise mindfulness
It can help to talk to people about how you feel. Sometimes the idea of talking about your treatment and feelings can be difficult. But speaking to your family and friends can often help you cope.
