Two new "breakthrough" drugs to treat breast cancer have been given the green light for use on the NHS.
The National Institute for Health and Care Excellence (NICE) approved palbociclib and ribociclib after negotiating prices for the treatments.
Research shows the drugs slow down advanced cancer for at least 10 months and can delay the need for chemotherapy.
Around 8,000 people in England will now have access to the medications.
There are around 45,000 new diagnoses of breast cancer in the country each year.
Palbociclib had earlier been rejected by NICE because of its high cost.
One cycle of palbociclib - or 21 capsules - costs £2,950 for a pack of 21. For 63 tablets of ribociclib, the price is the same.
The latest draft guidance from NICE said that women with oestrogen receptor positive breast cancer that is diagnosed after it has begun to spread will be eligible for palbociclib - also known as Ibrance.
If they have gone through the menopause, they will be eligible for ribociclib - also known as Kisqali.
The two medications are the first of a new type of drug shown to slow down the progression of cancer by inhibiting two proteins - CDK 4 and 6.
They only need to be taken once a day, alongside an aromatase inhibitor - which blocks the production of the hormone oestrogen and can fuel some breast cancers.
Nicholas Turner, professor of molecular oncology at the Institute of Cancer Research in London, and consultant medical oncologist at the Royal Marsden, said the new drugs were "one of the most important breakthroughs for women with advanced breast cancer in the last two decades."
Prof Turner, who led the clinical trials for the drugs, said: "Palbociclib and ribociclib have made a huge difference to women's lives - slowing down tumour growth for nearly a year, and delaying the need for chemotherapy with all its potentially debilitating side-effects.
"These drugs have allowed women to live a normal life for longer." Agencies
