some useful bits from the linked article:

“The researchers estimated that the absolute excess risk of developing breast cancer over a 15-year period in women with five years use of oral contraceptives ranged from eight in 100,000 women for use from age 16 to 20, to 265 in 100,000 for use from age 35 to 39. …

‘These excess risks must, however, be viewed in the context of the well-established benefits of contraceptive use in women's reproductive years.’”

that’s 0.008% to 0.265% increased risk over those who did not use hormonal birth control

No, those are the percentage risks of developing breast cancer for two different age groups, who BOTH took birth control. Using hormonal birth control in later life carries a higher risk of breast cancer, but as the percentages illustrate, the absolute risk is still low.
