Breast cancer symptoms appear in babies in a new study that shows signs are beginning to show in younger children.
The study, published online in the journal Pediatrics, was conducted by the Johns Hopkins University’s Child Health and Development Research Center.
The research team examined data from more than 9,000 babies from six countries, including Norway, which had the highest rate of breast cancer cases among the nations surveyed.
The data were analyzed to determine if the babies had higher rates of cancers that were diagnosed at age 1 and had them grow up to have them later.
The babies who had higher breast cancer rates at age 2 and later in life had an overall increased risk of developing the disease at age 7, while those who were younger at the time had lower rates.
The researchers found the babies whose breast cancer had progressed at the age of 2 had an increased risk for developing cancer in adulthood.
The risk for those with cancer at age 9 and later was even higher.
Breast cancer, a potentially fatal disease, can cause tumors of the breast and other organs.
Symptoms of breast or ovarian cancer are typically seen in young children, and symptoms can vary from mild to severe, depending on the cancer.
The cause of breast and ovarian cancer has not been determined.
The Centers for Disease Control and Prevention reports that about 13 percent of Americans will develop cancer at some point in their lives.
The National Cancer Institute estimates that one in five women will develop breast cancer at any given time.
Some researchers say the breast cancer rate could be reduced by reducing the amount of time it takes for women to have babies, particularly younger women.
However, the study does not show that having children reduces breast cancer risk.
The authors of the study said the findings provide evidence that children’s risk of breast, ovarian, and colorectal cancer increases with age.
However a study published in the Archives of Internal Medicine this week found that women who had breast cancer in their 40s and 50s were at greater risk of later cancer.
Some experts say older adults are at a higher risk of cancer, including cancer of the uterus, cervix, and breast.
