- How we can help
The symptoms of secondary breast cancer depend on which part of the body the cancer has spread to.
You may also have some general symptoms. These can include:
- feeling more tired than usual
- losing your appetite
- feeling generally unwell for no obvious reason.
These symptoms can be caused by other conditions. But speak to your GP, cancer doctor or specialist nurse if you have any of them. Always tell them if you have new symptoms, especially if they last more than 1 or 2 weeks.
The symptoms we mention here may make you feel anxious or frightened. But there are different treatments that help control the cancer and relieve these symptoms. We have more information about controlling symptoms of secondary breast cancer.
The most common symptom of a secondary breast cancer in the bone is an ongoing ache in an area of bone. It may be painful when you move around. You may find it difficult to sleep because of the pain.
Secondary breast cancer in the bones may also cause other bone problems. These include:
- high levels of calcium in the blood (hypercalcaemia)
- a break in a bone
- pressure on the spinal cord called spinal cord compression, which needs urgent treatment.
We have more information about controlling the symptoms of secondary breast cancer in the bones.
The first symptoms of a secondary cancer in the lungs can include:
- feeling breathless
- a cough that does not get better.
Sometimes cancer cells in the tissues covering the lungs (pleura) cause fluid to build up. This is called a pleural effusion. It can make you feel very breathless.
We have more information about treating the symptoms caused by secondary breast cancer in the lungs.
- feeling sick
- losing your appetite
- feeling very tired and generally unwell.
Sometimes, secondary cancer in the liver causes a build-up of bile in the blood. This is called jaundice. Symptoms include yellowing of the skin and whites of the eyes, and itchy skin.
Secondary breast cancers can sometimes develop on or just below the skin. This is called skin secondaries or metastases. This may happen in some women who already have secondary breast cancer.
Secondary breast cancer in the skin is not the same as local recurrence. With a local recurrence the cancer comes back in the treated breast or scar, but there are no secondary cancers anywhere else in the body.
Secondary cancer that affects the skin may look like either:
- a firm painless lump on the skin or many lumps of different sizes
- an area of skin that is red and swollen (inflamed).
Other possible symptoms include pain, bleeding, and sometimes infection.
Skin secondaries can appear near the area of the primary breast cancer, such as the skin of the chest or around the scar. Less commonly, they may develop in other areas of skin, such as on the scalp, neck, back and upper limbs.
A secondary cancer in the brain may cause symptoms such as headaches and feeling or being sick. These symptoms are caused by increased pressure in the brain. They may be worse first thing in the morning.
Other symptoms will depend on the part of the brain that is affected. They can include:
- weakness or numbness in an arm or leg
- loss of balance
- changes in mood or personality
- seizures (fits).
It is normal to feel very worried about a cancer that affects the brain. Treatment can usually quickly control the symptoms of a secondary cancer in the brain.
Sometimes, breast cancer cells spread to tissue that covers the brain and spinal cord (meninges). Doctors call this meningeal metastases or carcinomatous meningitis. It causes symptoms similar to a secondary cancer in the brain.
