Is breast cancer be related to the environment?

Yes. App. 10-15% of all breast cancers are believed to be related to hereditary risks; therefore, in a sense, the other 85-90% are related to "environmental" factors. Unfortunately, we don't know what specific triggers are responsible for breast cancer development; but, we do know that breast cancer occurs much more frequently in developed countries. This, regrettably, is a disease of modern life.
Possibly. It is possibly related to the environment. Also genetics, hormones and other factors are at play.

Is breast cancer genetic or caused by the environment or both?

Both. Only 10-20% of breast cancers are genetically related. We are not sure what causes the remainder, but environmental factors (such as the organochloride pesticides that were sprayed 30-50 years ago) are potentially responsible. Estrogen replacement is contributing to some, and the fact that women are living to be older with each generation increases the number of elderly breast cancer.

Could my breast cancer have been caused by the unhealthy environment I lived in for two years? Small lump started before I moved from the apartment, and now its the size of my palm (red and irritated too) it started 9 months ago. No history of any cancer

Not likely. One factor is family history of this disease, like if a sister and mother also had it. These cancers are hormone dependent, so early menarche, late menopause, and late/no term pregnancies are at increased risk. Dietary fat intake may also be a risk factor. But the environment you lived in is highly unlikely to have done this. More likely is that you should've seen your dr. So see dr. Asap.
UnRx'd Cancer Grows. While it is true that as many as 90% of all breast cancers are environmental in origin, it is difficult if not impossible to identify the specific cause of your cancer.

Why does one of my breasts sag more than the other? Could this be related to breast cancer? 33 year old female.

Not certain cancer. The left and right sides of our bodies are never perfectly symmetrical so the fact that the breasts are not mirror images of each other is not concerning. However, if you're saying that one of your breasts looks different than it usually would look, then you would really need an investigation including an exam and mammogram at least.

About 5% of women with breast cancer carry a mutation in brca1 or 2 women with brca1 mutations also have a 20 to 40% lifetime risk of developing ovarian cancer; risk among women with brca2 mutations is increased less men who carry a brca2 mutation also have an increased risk of developing breast cancer the genes are more c.
Very high risk. Patients who are brca positive have a very high risk of developing breast cancer. They can have an 80-90% risk (over lifetime) of developing 1 breast cancer, 50-65% chance of developing a 2nd breast cancer and a 40-50% risk of developing ovarian cancer.

I feel throbing pain from my left breast to my left side of my back bone. I am kind of worried if it is related to breast cancer.

Breast pain. Unlikely breast cancer, sounds more like an inflammatory cause. Please see your doctor and get proper evaluation with labs and possibly mammogram or ultrasound if there are abnormal findings on your exams.
Probably not. Breast pain is not a common symptom of breast cancer and it would be rare for a 28 year old female to develop breast cancer. This is most likely benign breast pain. However you should discuss your concerns with your friendly primary care physician.

It can weaken the immune system, in particular, and that alone makes one more susceptible to cancers of all types. In addition, if circulation is impaired, your immune system cannot send the killer antibodies it needs to kill the tumor cells.
