It comes after Eugenie marked her 34th birthday with a tribute post dedicated to 'the best gift of all' - her children.

The daughter of the Duke and Duchess of York took to Instagram last month to praise her two sons, August, three, and Ernest who is about to mark his first birthday.

In the candid photograph, Eugenie playfully held her younger son, Ernest, aloft in her arms.

The 34-year-old's decision to cherish family on her special day comes amid a troubling time for the royal family following the news that King Charles III, 75, Kate, 42, and Sarah Ferguson, 64, are all facing cancer battles.

In light of this, Eugenie captioned the post: 'The best gift of all are my boys... so on this birthday I'm cherishing family and loved ones.'

To mark her 34th birthday, Princess Eugenie shared a sweet photograph with her youngest son Ernest on Instagram 

Princess Eugenie marked her birthday two days after the announcement that her cousin's wife, the Princess of Wales, is battling cancer, the third member of the royal family to be diagnosed in recent months.

Princess Beatrice and Eugenie's mother, Sarah Ferguson, was diagnosed with skin cancer just months after having a mastectomy for breast cancer. Their uncle, King Charles, is also undergoing cancer treatments.

Nonetheless, in an optimistic fashion, Eugenie shared a thoughtful message celebrating family on her special day. 

Looking typically chic, Eugenie donned a short-sleeved caramel jumper with a chunky signature headband in the image.

The mother-of-two accessorized her look with a pair of emerald earrings and a simple yet elegant gold chain.

Meanwhile, Ernest looked smart in a pair of blue corduroy trousers and a matching knitted jumper.

Elsewhere, Sarah Ferguson, also took to Instagram to praise Eugenie on her birthday.

In a sentimental post, Sarah hailed her daughter as an 'incredible woman' with 'silly, sweet, smart, and thoughtful' qualities.

Sarah Ferguson, 64, also shared a sweet photograph on Instagram to mark Eugenie's 34th birthday 

The Duchess of York called her daughter an 'incredible woman' with 'silly, sweet, smart, and thoughtful' traits 

The mother-of-two shared a causal picture of herself with Eugenie with a stunning countryside backdrop. 

Dressed in lowkey hiking attire, the pair sat on a rock while Sarah sweetly pecked Eugenie's cheek. 

She wrote: 'Happy birthday to my amazing daughter. I am so proud of the incredible woman you have grown up to be. 

'You continue to amaze me every day in your hard work, your grace, kindness, and the care you show to others. 

'You will always be my silly, sweet, smart, and thoughtful girl. I love you, Eugenie. Happy birthday.

It comes after Princesses Beatrice and Eugenie rallied together last Thursday as they headed for lunch in central London amid the royal family's health woes.

For the outing birthday girl Eugenie opted for a burgundy coat with knee-high black boots and sunglasses.

She accessorised her green and blue dress with a cream and leather handbag, and protected her eyes from the sun with aviator glasses.

The royal mother-of-two had earlier in the day read to children from Garden House School at Elephant Family's Little Egg Hunt in Sloane Square.

She opted for a natural make-up look for the occasion, letting her hair down and loose.

Meanwhile, big sister Beatrice, 35, tied her tresses up into a chic messy bun.

The royal, whose father is Prince Andrew, opted for a scholastic-inspired look with black dollie shoes, and long grey skirt and cardigan. 

Showing off her natural beauty, Beatrice opted for a minimal make-up look as she chatted on the phone.

The pair are now likely rallying together amid various health scares in the Firm.

Both Beatrice and Eugenie are close to their cousins Prince William and Prince Harry - and are likely to be shocked by the news of Kate's diagnosis.

It comes after the Duchess of York has had a mole removed from her body which tests have since found to be a malignant melanoma which is the most serious type of skin cancer.

The mother-of-two had a number of moles removed while undergoing breast reconstruction surgery last year, one of which was found to be malignant.

The Duchess, who is the ex-wife of Prince Andrew, was described as being in 'good spirits' after the 'distressing' news, which was broken to her just days after Christmas.
