Q. Should I be worried – I’ve been invited for a breast screening appointment?

A. Breast Screening aims to find breast cancers early. Women aged 50-70 are invited to have an X-ray test called a mammogram that can spot cancers when they are too small to see or feel.

Breast screening is offered to women aged 50-70 in England registered with a GP every three years. You may be eligible for breast screening before the age of 50 if you have a higher-than-average risk of developing breast cancer, such as a family history.

If you're over the age of 70, you'll stop receiving screening invitations. However, you're still eligible and can arrange an appointment by contacting your local screening unit.

Screening is carried out at special clinics or mobile breast screening units. It is carried out by female members of staff who take mammograms.

During screening, your breasts will be X-rayed one at a time. The breast is placed on the X-ray machine and gently but firmly compressed with a clear plate. Two X-rays are taken of each breast at different angles.

The mammogram will be checked for any abnormalities. The results of the mammogram will be sent to you no later than two weeks after your appointment.

Following screening, about one in 25 women will be called back for further assessment. Being called back doesn't mean you definitely have cancer. The first mammogram may have been unclear. The programme is important as if breast cancer is detected early there's a really good chance of recovery.

Q. I feel unwell when travelling as a passenger in a car – please help.

A. Motion sickness is feeling sick when you travel by car, boat, plane or train. It’s caused by repeated movements when travelling, like going over bumps in a car or moving up and down in a boat.

The inner ear sends different signals to your brain from those your eyes are seeing. These confusing messages cause you to feel unwell.

There are things you can do to prevent it or relieve the symptoms.

Minimise motion by sitting in the front of a car or in the middle of a boat. Look straight ahead at a fixed point, such as the horizon and breathe fresh air if possible, for example, by opening a car window

Close your eyes and breathe slowly while focusing on your breathing. Distract children by talking, listening to music or singing songs. Break up long journeys to get some fresh air, drink water or take a walk.

There are things to avoid if you are prone to travel sickness. Don’t read, watch films or use electronic devices. Don’t look at moving objects, such as passing cars or rolling waves. Don’t not eat heavy meals, spicy foods or drink alcohol shortly before or during travel – and don’t go on fairground rides if they make you feel unwell.

A pharmacist can help with motion sickness and recommend the best treatment for you or your child. You can buy medication including:

• tablets – dissolvable tablets are available for children

• patches

• acupressure bands – these don't work for everyone
