Breast Cancer: Symptoms, Causes, Genetics and Genetic Testing

May 11, 2010

Breast cancer is defined as cancer that originates in the breast cells. Women are 100 times more likely to develop it than men. It is the second most common form of cancer after lung cancer. Every year about 200,000 American women are diagnosed with breast cancer. It killed half a million people in 2005.

Breast cancer can spread through the lymphatic system or blood vessels to other parts of the body. This spread is referred to as metastasizing. It can metastasize to the lungs, brain, liver or bones.

There are non-specific and specific symptoms. Non-specific means that they could be symptoms for some other condition. Some non-specific symptoms include:

  • bone and joint pain
  • chills
  • discharge from one nipple
  • fever
  • jaundice.

Some specific symptoms include change in the size or shape of the breast or nipple and a lump in the breast or the lymph nodes in the armpit and/or collarbone

Inflammatory breast cancer occurs when breast cancer cells enter the small lymph vessels next to the skin. Symptoms include:

  • orange peel texture of the skin
  • pain
  • redness
  • swelling
  • warmth.

Paget’s disease of the breast also manifests itself in the skin and resembles eczema. Symptoms may include:

  • discharge
  • itching
  • lump
  • mild flaking of the skin around the nipple
  • redness
  • sensitivity
  • tingling.

Causes of Breast Cancer

Breast cancer stems from a combination of hereditary and environmental influences. People who have a family history with multiple cases of breast or ovarian cancer are at higher risk of getting breast cancer. Breast cancer is more common if one has an Ashkenazi (Eastern European) Jewish background. It usually occurs sporadically and is not inherited. Some risk factors include:

  • age
  • alcohol intake
  • childbearing
  • environmental factors like radiation and tobacco use
  • high fat intake
  • hormones
  • obesity
  • sex.

Genetics of Breast Cancer

About 5-10% of those diagnosed have a hereditary form of breast cancer. If a person inherits a mutation in the breast cancer 1 (BRCA1) or breast cancer 2 (BRCA2) genes, she is at higher risk of developing breast cancer. It is rare to inherit a mutation. Only one in 1000 has a mutation in one of these genes.

People who have the mutation may get cancer or may lead a long healthy life. Having a mutation does not guarantee the individual will develop cancer. About 13% of the population develops breast cancer. Those with a mutation in either of these genes are three to seven times more likely to get it.

How Genetic Testing Is Done for Breast Cancer Patients

Genetic testing looks at sequences of DNA to identify changes. The sequence of DNA has been determined for healthy people. If there is a mutation in a gene, it can make a person more susceptible to certain diseases. Certain inherited conditions have been linked to mutations in certain genes. Genetic testing is the comparison of the sequence of sample DNA to the agreed upon sequence for a normal gene to identify these risks.

Genetic testing for breast cancer is only performed on people who are at high risk of getting cancer. This blood test identifies the presence of mutations in the BRCA genes. A breast cancer genetic testing lab determines the patient’s risk of getting cancer. Genetic counseling is included in this test to make sure people are informed of their risk and options for the future.

Progress toward a Cure

Treatment for breast cancer today relies heavily on surgery, chemotherapy and radiation. Gene therapy is one option of curing breast cancer. It is not yet possible, but eventually doctors will be able to fix the mutations in the genes. Research continues to search for more genes that influence a person’s risk of developing breast cancer.

Some ways to prevent breast cancer include:

  • Chemoprevention – Some medications, such as tamoxifen, decrease one’s chance of developing cancer.
  • Mastectomy – Preventative removal of breast tissue reduces the risk of cancer by 90%.
  • Surveillance – More frequent self-exams, clinical exams, MRI’s and mammograms discover cancer earlier.

Nutritional Tips for Mother-to-be, Mother and Infant

January 4, 2009

What to Eat While you are Pregnant

A pregnant woman should not diet. Baby needs a certain amount of nutrition to grow and thrive. She needs to eat 300 extra calories per day. These calories are the amount of energy supplied by the carbohydrates, protein and fats in foods. But these calories should be from nutritious foods, not empty calories.

Protein is made up of the most important building blocks that will make your baby. Pregnant mother-to-be should have no fewer than 60-75 grams of protein per day. This would equal three servings. These can include: milk, cheese and cottage cheese, eggs, yogurt, tuna and sardines, seafood, salmon and other fresh fish, poultry and meat.

Pregnant women need an adequate and continuous supply of iron for both themselves and baby. The daily recommended intake of iron is 27 mg. Some foods rich in iron include iron-fortified cereals, spinach, dried beans, peas, potatoes, lentils, dried apricots, oatmeal and lean red meat. Your practitioner should inform you if you need an iron supplement.

Iron can block the body’s absorption of zinc. Zinc is essential for the development of your baby’s brain and nervous system. Therefore, mom-to-be needs to eat zinc-rich food, such as fish and wheat germ, separately from iron-rich food. The daily recommended intake of zinc is 11 mg.

Remember to always take your prenatal pills. These will have a basic supply of what you need for the day. But they will not be sufficient alone. It must be supplemented with a good diet of healthy foods as well. Friut, vegetables, lean meat and whole grains are very important. Water and drinks that have no caffiene should be consumed liberally. Drink at least 12 cups of water a day.

Eat wild salmon frequently – brain development is going on like crazy for your baby now. It is also needed for lung surfactant. But it’s not just omega fatty acids – you have to eat the fish. Many grocery stores sell frozen fillets of wild salmon at a reasonable price. If you can not find wild salmon or it is too expensive, eat farmed salmon.

Nursing

Feels strange doesn’t it? So many receptors in our brain for that event have been growing in you while you were pregnant. Oxytocin stimulation is changing your behavior – making you into a good mom. Give in to that happy clam feeling and don’t let your rational smart brain interfere with the normal day to day. Take lots of video, as I think this time really doesn’t allow for memory making – maybe because of the other things going on biologically. Small frequent meals may help you fell less emotional. Drink decaf tea but give up coffee for a month or two……

Keep breast feeding if you can or pump and feed breast milk from the bottle. Avoid formula if you can for the first three months until the intestinal tract is a better barrier. Drink lots of liquid and pump. Formula will change the epithelia of the intestinal tract. Continue eating salmon. The blood brain barrier: brain development is still in full swing up to three months after birth.

Some tips


One should plan on feeling a bit blue and this is natural. Don’t skimp on the salmon as this may help that feeling. Your breast must supply fat for your baby and unfortunately the richest source is your brain! There has been some research suggesting depression postpartum may be linked to this but the evidence is sparse. Unfortunately, most of 21st century women don’t eat enough fish. So when our babies develop they steal the smaller amount we have.

Minimize your corn and safflower oil intake and avoid margarine. Switch to olive oil.

Take naps when the baby does; just drop into his little circle of life. Your brain will help you stay connected to him, hear him, respond to him – but try not to feel anxious. Let your biological reflexes take over. You’ve got two million years of reproductive development behind you.

Definitely don’t worry about any messes or cleaning. It is not going anywhere. Maybe dad or a friend can help out. Always accept help when it is offered. Someone coming over to visit the baby will not mind picking up some lunch on the way and will actually appreciate being able to be helpful. Feel free to allow neighbors to walk to dog – just offer a leash and a plastic bag. When baby is older, Doggy will be happy to join you on your walk down the street.

If you have to go anywhere, remember to do a lot of handwashing and infection control until he’s at least 6 weeks. I would only let persons living with you hold him. Especially, don’t you get sick – as you might give it to him. A friend’s baby got a cold at less than 6 weeks, they went to the hospital and doctors insisted on a spinal tap – horrible..

What you need to feed your older baby

Until the baby’s sixth month most nutritional requirements are filled by breast milk or formula. After this time, however, baby’s dietary needs will be supplemented by other sources. By 9 months baby will be eating a variety of foods to make meal time more fun and nutritious. Meat is a good source of protein, iron and zinc. Protein is very important since it is made up of amino acids, which are the building blocks of which your baby is made. Baby needs about 1.5 grams of protein per 1 kilogram of body weight. This can be most easily supplied by straight potted meat and eggs (when they are introduced). Baby should eat a high iron fortified cereal each day.

 

Breastfeeding is Good for Mother and Baby

January 4, 2009

breastfeeding1Mothers find many reasons to excuse themselves from nursing their baby. Although some are valid, quite a few are not completely fair to the baby. The benefits of feeding a baby breast milk are far too important to give a half hearted effort and decide to give up. Especially after a difficult birth, it is not easy to try to “force” the little one to latch on and suck. This is even truer when the breast does not give forth much milk until several days after birth. Even if mother has to supplement with formula, a small amount of breast milk does wonders for the newborn.

Nursing also brings about benefits for mother. The hormone oxytocin is released into the mother’s body giving her a motherly feeling. It helps the bonding occur between mom and baby. You may not be your same rational self, but give in to the happy feeling. Also, your memory will not be what it was before, but that is why you take pictures and videos. The loss of memory is probably so you will agree to do all this again without thinking about all the sleepless nights!

Be aware that the breast may become infected. When a milk duct within the breast or under the armpit becomes blocked, an infection may occur. The area becomes swollen and red. It is warm to the touch and mom gets a fever. Call or see your doctor and ask for antibiotics as soon as possible. This can be very dangerous if not treated. Continue feeding from this breast and attempt to drain it first before starting on the second breast. A warm compress can be placed on the breast.

Pumping milk from the breast has made it easier to feed the baby even if breast feeding is too uncomfortable. It makes mom feel a bit like a cow when she looks down and sees milk squirting out of multiple holes in the nipple, but remember this is for baby. This allows dad to bond with baby as well. It can give mom a rest during the middle of the night. There are little tubes attached to a syringe so parents can trick baby into thinking it is sucking on the breast when it is actually sucking on a finger. This is important since baby must not bottle feed in the first month or else it will prefer the bottle over the breast since the bottle is easier to get milk out of.

Please try to nurse baby for a week before you quit. If it is not working at this point, please pump what you can and feed it with formula. But don’t stop just because it feels funny, is inconvenient, you are too shy or you want to indulge in alcohol or drugs. Wait at least two hours after each drink before nursing or pumping. If you still feel drunk, there is a good chance the milk will come back up if you try feeding it to baby. In any case, drink a lot of nonalcoholic fluids to increase milk production and pump and store some when you can. You never know when you might need it.

Good luck!
